1. Troy Lee Designs Stage: Full -faced  helmet for downhill MTB | Overall best choice

Troy Lee Designs Stage Helmet

  • Helmet Coverage: Full Face
  • Use: Enduro
  • Sizes: XS/S, M/L, XL/XXL
  • Weight: 685 g (size M/L)
  • Shell: Fiber-reinforced Polylite shell
  • Inner: Dual-density EPS and EPP foam with 3D XT2 cheek pads and X-Static
  • Protection: MIPS
  • Ventilation: Vent Holes
  • Number of vents: 25 (11 high-flow intake ports and 14 exhaust vents)
  • Chin Bar: Polyacrilite injected with EXOskeleton
  • Visor: Yes (Anodized aluminum visor hardware)
  • Fit: Fidlock® magnetic buckle
  • Certifications met: CPSC 1203, CE EN1078, ASTM F1952, ASTM F2032, and AS/NZS 2063-2023
  • Color: Black, Black/Pink, Grey, Race Black/Red, Race Silver/Navy

Features & Considerations
  • MIPS: Also known as Multi-directional Impact Protection System, it is the most popular slip-plane technology that can reduce rotational force impact.
  • Ventilation: The chin bar has five open cutouts, and we find the wide one central ventilation cutout in the front and center. Two more long, wide cutouts are present on the chin bar and are directed towards the cheeks. Two smaller vents are seen in the middle of the central cutout and the ones on the side of the bar. These cutouts do not feature mesh design and are wide open.
  • Visor: The Stage MIPS helmet has a sizable and broad visor. There is about 2.5-3-inches adjustment. The visor can be adjusted by using a single dial. The dial is small but has three short extension pieces that are half-inch respectively. On the small side of the spectrum, there are three short and half-inch extension pieces. They stick out from the main dial and are easy to grab, even when you are wearing the helmet.
  • X-Static: This a special material used in padding that can kill 99.9% of odors and bacteria. It is created with real silver fibers, which makes X-static the quickest drying padding available.
  • Fidlock magnetic buckle: Fidlock has improved the fastener system by using a combination of magnetic and mechanical mechanism, which makes the buckle sturdy and convenient.
  • Chinbar: The chin bar has been lined with EPP foam that refers to Expanded Poly Propylene foam. It looks similar to EPS but with a surface. Since it is a multi-impact foam; it can regain its original shape after a crash.

Some Weaknesses
  • The chin bar may feel tight.
  • The chin straps have no padding.
  • Narrow design means there’s not enough room for the goggles under the visor.
  • Fidlock closure may not suit everyone.

Available in three sizes, the TLD Stage comes with a variety of pads with different densities that are interchangeable. They are used to customize the fit as there is no adjustable retention system present. You will find two-liner thicknesses (13 mm and 10 mm) which will sit over the MIPS device, two neck rolls (25 mm and 15 mm), and three-jaw pads (35 mm, 25 mm, and 15 mm). They are all labeled for easy identification. Customer convenience is important for the company to make its full-face mountain bike helmet the best.

When you have figured out what pad configuration provides the best fit, you can be sure that the helmet will stay snug on your head without any slipping or creating any uncomfortable pressure points. Most people will use goggles with the stage – that helps to make the helmet more stable. Even if the chin bar may seem a little tight-fitting, but this allows the rider to have an unobstructed view that will add to the rider’s confidence. Even on long climbs and hot temperatures, this helmet seems pretty comfortable owing to the 25 generous vents and the fact that the helmet is relatively light. This helmet meets a wide variety of safety standards – CPSC 1203, CE EN1078, ASTM F1952, ASTM F2032, and AS/NZS 2063-2008. You will also find the MIPS feature inside the helmet. There will be a yellow-colored layer beneath the padding but above the foam shell. This layer is intended to move a bit in the event of an impact that is an angled/off-axis impact. As the liner shifts, it minimizes the rotational forces that reach your brain. We can find a simple chin strap that can rub against the ears slightly, and can be fixed using a convenient magnetic Fidlock buckle that is easy and quick to secure in comparison to a typical D-ring system.
The lightweight and good ventilation make the Troy Lee Stage our overall best choice for long shuttle days and enduro race – in turn, the best full-face mountain bike helmet from our perspective. We have included a sizing guide to help you find the perfect fit:

2. Bell Super DH: A versatile & lightweight full-face helmet

Bell Super DH Helmet

  • Helmet Coverage: Full Face
  • Use: Downhill and Enduro riding
  • Number of Sizes: XS/S, M/L, XL/2X
  • Weight: 850 gm(Size M)
  • Shell: Fusion in-mold Polycarbonate Shell
  • Core: Variable density EPS with Sweat pad + X-static
  • Protection: Flex Spherical + MIPS
  • Ventilation: Overbrow Ventilation
  • Number of vents: 19 vents, 2 brow ports, 4 chin bar vents
  • Chin Bar: Removable Wraparound
  • Visor: Goggle Guide adjustable visor system
  • Fit: Float Fit with Fidlock magnetic buckle
  • Certifications met: CPSC Bicycle, CE EN1078, ASTM F1952-00 DH, and ASTM F2032-06 BMX
  • Color: Fasthouse matte gloss red-black, Matte gloss sand black, Matte gloss blue hi-viz, Matte gloss black camo, Fasthouse stripes matte black white, Unhinged matte gloss blackberry blue, Matte gloss crimson black, Matte gloss slate orange, Matte gloss yellow black

Features & Considerations
  • MIPS: The Multi-Directional Impact Protection System (MIPS) redirects rotational energy and provides better protection in certain impacts.
  • Spherical Flex: This flex is the most advanced feature that incorporates a design to deal with linear and rotational energy in the head in low, medium, and high-velocity impacts. This flex is becoming very popular for protection.
  • Progressive Layering: This is an engineering process that uses a helmet liner with EPS foam of variable densities so that after an impact, the transfer of energy can be managed in a better way.
  • Versatile helmet: A perfect fit when you need both a full-face helmet for local trails and a half-shell to be used in a bike park. The Polycarbonate shell makes the helmet feel more like a fiberglass or carbon full-face helmet, but it surely does not compromise on anything else except weight. The wrap-around chin pad is removable to turn it into a trial helmet.
  • Wraparound Chin Bar: The wraparound chin bar is made for enduro, all-mountain, and heart-pounding trail rides. It gives the rider full, extended protection – with lower rear coverage plus uncompromising comfort and ventilation.
  • GoggleGuide adjustable visor system: You can use goggles with most MTB helmets. However, the Bell Super DH accommodates a set of goggles with visor systems so that they don’t get lost and are always in the correct place. An adaptable visor system accommodates both goggles and glasses and works with or without the visor attached.
  • Breakaway action camera mount: We have a bracket that has been built so that a GoPro camera can be fitted onto it. Velcro screws help to fit this bracket into an air vent that is found at the front and center of the helmet. This allows a seamless integration onto the helmet and removes the necessity of sticky-backed mounts.
  • Overbrow Ventilation: This system is perfect for trail riding and actively directs cool air over the head via four intake ports that are present on the brow of the helmet. There is a specially designed bridge that keeps the ducts free from any obstruction. Additionally, Super’s air-channel matrix works in coherence with the helmet’s 25 vents so that high-speed airflow can be achieved while at low speeds.
  • Inner lining: The inner lining of this helmet has a sweat guide pad design that removes moisture away from the brow pad and also from the eyewear. We also find the X-static padding that has quick drying properties and cleans bacteria.
  • No-Twist Tri-Glides: These quick-adjust fasteners ensure that the helmet straps are in their optimum positions and also flat.
  • Float Fit with Fidlock Buckle: Float Fit DH features an over-molded and easy-to-turn rubber dial fit system that will ensure the best possible level of comfort in terms of fitting on the rider’s head. The SNAP Fidlock Buckle found here locks in automatically and can be opened easily with two fingers.

Some Weaknesses
  • Flimsy straps can twist and eventually become loose
  • The heavy magnetic buckle can cause discomfort to your neck.
  • Wider and less ventilated.
  • While turning the half-shell mode on, the rider may experience pressure points at the back of his head.

The first thing you notice is that the Bell Super DH helmet uses a total of 25 vents in all. The elongated back profile means that the helmet provides more protection and we find that there is a significant amount of padding present inside the helmet. This portrays that this helmet offers more protection. The Super Dial fit system features an adjustable cradle at the back of the helmet that is easy to use and adjust. This cradle will allow you to adjust the shell in 3 positions.

The “Overbrow” ventilation works well by allowing air to slip in from the top of the forehead to the back of the skull and helps to regulate temperature. The Super DH padding is thicker and comfortable. The cheek padding is also very cushy and the package includes an extra set of pads. They snap in and out easily in case of an emergency or if they’re just getting smelly and need to be washed. The soft padding does a great job of wicking sweat too, making it comfortable even during long hours of riding on hot days. Bell has employed the latest MIPS safety liner inside. This technology reduces the likelihood of skull and brain injuries by sliding the inner surface that dissipates any rotational forces that are generated in a crash. The Super DH is offered in 3 different sizes – XS/S (54-56 cm), M/L (57-59 cm), XL/2X (60-62 cm).

Some Weaknesses
  • There is no center screw on the visor. So, it may rattle during riding.
  • You may need to constantly check for proper fitting of the magnetic buckle.

The Bell Full-9 helmet meets the ASTM Downhill Mountain Bike Racing, CPSC, and CE bicycle safety benchmarks, making this helmet one of the safest helmets available in the market. For a quick review, we can start with the specially designed Flying bridge that makes sure that the ducts are free from obstruction while ensuring maximum full-head ventilation via the helmet’s internal air-channel matrix. Overbrow ventilation pulls in cool air and the Velocity flow ventilation collaborates to deviate the cool air over the rider’s head using three ports that can be found on the brow of the helmet. The Eject helmet removal system and magnetic cheek pads work together so that the cheek pads can slide out and allow the helmet to be removed quickly from the rider’s head to minimize the risk of any secondary injuries. The Magnefusion removable magnetic cheek pads can also be removed between for quick drying.

  • The helmet has a bulky look.

The Fox Proframe Helmet is one of the lightest full-face helmets that offers good breathability. With a more streamlined design, it won’t leave you with your head hanging after an all-day ride. Its low weight means that it can be used both in enduro and downhill for its  DH-level protection with the superlight shell using their patent-pending, fully integrated chin bar. Also, you will not have to experience the discomfort that comes with a hot and heavy full-face helmet.

15 Big Bore intake and 9 exhaust vents allow sufficient airflow and help breathability so that even on the longest and most challenging climbs, you do not heat up. The helmet keeps your ears and head considerably warm on cool days but does not turn you into a sweat bucket in the summer months. The highly breathable liner system is tucked into a shell that is super light and the fixed visor is securely positioned to allow airflow into the Big Bore vents. Although the visor is fixed, it does not obstruct vision and the rear molding keeps goggles straps securely positioned.

For long uphill climbs, you can take the chin bar off and keep it in your pack. Whenever you want to take on aggressive riding, simply attach this chin bar by locking it in without any extra tools. So, you are getting two helmets for the price of one!
  • MIPS: This technology engineers a slip plane designed to bring down energy from rotational and angular forces from certain crashes.
  • Overbrow ventilation: During fast rides, the air is cooled and goes into the helmet and distributes the air through the channels.
  • Googleguide™ Adjustable Visor System: An adjustable visor system that works with goggles or sunglasses, whether the visor is mounted or disassembled. You can adjust the visor in three positions.
  • Integrated Breakaway Camera Mount: Bell’s built-in camera is mounted and you can attach it easily without any tape or cable ties. The detachable attachment for the camera is fitted at the helmet top to provide ventilation. The camera stays firmly in place and can be removed easily.
  • X-Static: Silver threads are used in the X-Static pads allowing the helmet to dry quickly. This also helps against odor and fights against the formation of fungi and bacteria. The thermal attributes of these pads will keep the rider warm in cold weather.
  • XT2 Padding: These paddings are absorbing the sweat that is washed away by the sweat pad. It keeps you dry and odorless as it is made using original silver fiber.
  • No-Twist Tri-Glide: These quick-adjust fasteners hold the straps flat in place and in the exact position where you want them.
  • Breakaway Screws: Bell’s visor screws will become loose easily in case of a crash to avoid the risk of cutting by bent visors.
  • In-Mold: In the process of in-mold construction, an outer shell is made from robust polycarbonate and is bonded to the EPS inner shell to boost the impact-absorbing abilities of the helmet without increasing weight. Manufacturers can now design lighter helmets with modern ventilation systems and openings.
  • Float Fit: This is a patented fitting system designed by Bell for the best possible level of comfort and protection in this helmet. Guide arms are enclosing the rear of the rider’s head using the “float” design so that the system is easy to handle and to help the helmet fall into the best possible position on the rider’s head. A suspended dial can be found at the back of the helmet that can be adjusted until the rider feels that the helmet has been secured using the “leaf-springs” of the fitting system’s design.

Some Weaknesses
  • Can interfere with sunglasses frames.
  • Heavier than some other trail helmets.
  • Mushroom-like aesthetic.
  • Must have a place (like a bag) to carry the chin bar when not in use.
  • When worn without the chin bar, the helmet is less secure.

The Bell Super 3R simply lets you take the chin bar off and store it in your pack while riding on long trails. Again when you are facing a more aggressive terrain, you can easily lock the chin bar without requiring any special tools. The helmet’s design makes it perfect for all types of all-mountain ridings such as climbing slowly for a long time and making downhill rides on wide but rough trails. The MIPS system works very well to provide additional protection for angled impacts on the helmet by minimizing rotational forces.

This combination of outstanding safety, optimized ventilation, and featherlight weight of the helmet will boost your performance on any trail. On hot days, when you may want to rally along desert rocks; you want a helmet that will help you to stay cool. Bell uses brow channels, helmet vents, and chin guard vents to keep the air moving inside the helmet. These are placed strategically all over the helmet body without weakening the helmet structure. Overbrow ventilation uses intake ports that we can find on the brow of the helmet to take in cool air and pushes it via the air-channel matrix so that the rider can experience full-head ventilation. Bell uses the new Float Fit DH as for the retention system, which allows for a great amount of adjustment and is coupled with their magnetic Fidlock buckle. In addition to the improved overall protection, Bell also added small features on the Super 3R like the integrated camera and light mount-a-breakaway design. There are breakaway screws all over the helmet that can be used for emergency removal. The adjustable visor has been integrated with a wide array of googles. Also, the X-Static padding promises to allow a comfortable fit.

Tips to buy the best full-face MTB helmet

There is a huge range of full-face mountain bike helmets that come equipped with safety features and the latest technological design advancements. These helmets vary in terms of mountain bike helmets, also vary in terms of size, weight, construction (shell + inner lining), ventilation, and comfort. They are designed to be suitable for specific MTB disciplines.

Types of MTB Helmets

    • Classic Helmets: The classic MTB helmets are highly sought after for being extremely light and for offering good ventilation. They provide efficient protection for the whole skull but focus less on the rider’s face. This type of helmet is particularly suited for entry-level practitioners as well as cross-country amateurs.
    • All-Mountain Helmets: All-mountain helmets, which use the same base as classic helmets have longer rears and can offer better protection for the neck. Despite being slightly heavy – they offer a good level of ventilation and are often used on mountain roads.
    • Dirt-Jump Helmet: Dirt Jump helmets are heavier and often less ventilated than classic MTB helmets. These bowl helmets are better suited for street or skate-park use and can guarantee greater security and safety on the back of the skull without compromising its style. This type of helmet is greatly appreciated by all BMX-freestyle amateurs.
    • Full Face Helmets: Usually, these helmets tend to weigh a bit more as it is not possible to bring down the weight of this type of very complete helmet. They also protect the entire face thanks to their special shape.
    • Hybrid Helmets: These helmets can change form with the single press of a button. They go from an all-mountain helmet for flat-rolling terrains to an integral helmet with the addition of a chin strap, which is better suited for more aggressive downhill riding. The MTB enthusiasts can easily use these helmets in the mountains. The chin bar is removable and can be converted into a half-face helmet that can be used for different endure stages. Riders can attach it back again to form a full-face helmet that suits aggressive trails such as downhill riding for better protection and safety.

Types of Full face helmets

Full Face helmets are split into two types:

    • Downhill or DH helmets: Downhill helmets are similar to off-road motorbike helmets, with internal padding and a minimized number of vents.
    • Enduro helmets: They have better ventilation and look similar to regular MTB helmets with an extra chin guard, which can also be removed. The chin guard on these enduro helmets are well vented for making breathing easier on climbs.

1. Shell

The shell forms the outer covering full-face helmets. With standard polycarbonate shells that are found on regular mountain bike helmets, full-face helmets sometimes can also be made from fiberglass or carbon. The shell can be molded to the core and completely cover the helmet – which also includes the chin piece. Typical materials used for the shell are:

    • PC (Polycarbonate): This is a strong and hard plastic material that can be shaped easily to form the outer shell when heated. This characteristic makes it perfect to make helmets using in-mold or Carbontech in-mold processes.
    • PETG (Polyethylene terephthalate glycol): This is also a hard plastic material that is used to make the outer of a helmet. It cannot resist heat like PC and is not preferred for in-mold production. PETG does not release toxic materials when heated and has become popular nowadays.
    • ABS (acrylonitrile butadiene styrene): This is a plastic material with more resistance to impact. ABS performs well in cold conditions.
    • Carbon: Carbon makes the helmet structure stronger and can be molded into the construction.
    • Aramid: Some helmet manufacturers may reinforce the in-mold mountain bike helmet by introducing a framework of Aramid fibers into the central part of the helmet. The inclusion of this synthetic material enhances protection and durability in an accident.

2. Core

The core sits underneath the shell. Typically, the core is made using EPS foam. Sometimes on high-end DH lids EPP foam is used. Multi-density foam cores are also preferred for better impact protection at variable speeds. Full face MTB helmets are strengthened using additional elements that reinforce the shell designs that have additional venting. Common materials used for the core are mentioned below:

    • EPS (expanded polystyrene): EPS is a high-quality plastic material that has an optimal density for impact absorption and to make the helmet durable and long-lasting. EPS forms the inner lining and absorbs the most impact during a crash.
    • EVA: EVA is a material that boosts the ability to absorb impact and is coupled with the EPS. EVA is very flexible but also tough.

3. Fit with Straps

Full face helmets use chin straps with the fitting systems. We explore typical fitting systems in full-face MTB helmets below:

    • Downhill helmets: With an extensive liner that wraps around the rider’s head, these helmets have cheek pads in the chin guard so that the helmet provides a better grip for the rider’s head on the inside. DH helmets feature D-ring style straps that are very safe.
    • Enduro style full face lids: Padding is minimum, but comes with adjustable fit systems. Snap-fit buckles sometimes have a supplementary cheek pad for a better fit.

4. Liner

The padded liners of full-face MTB helmets come in direct contact with your head. If you are a frequent rider, you can go for liners that are made from materials with quick-drying, anti-microbial properties. These can also be removed and washed. Full face MTB helmets can be customized for a better fit using extra paddings that are sometimes provided with the helmet. Variable padding of different thickness is more preferred due to the better fit and comfort.

5. Ventilation

Full face MTB helmets have an efficient ventilation mechanism. Mostly, full face MTB helmets have such advanced and innovative designs that keep the level of ventilation similar to that of open face helmets. It is important to choose a helmet that will favor you in tough and hot conditions by keeping you cool and dry. Typically, downhill MTB helmets have minimal ventilation as riders will have a naturally fast speed which will automatically improve airflow. Enduro full-face MTB helmets feature extensive ventilation for both uphill and downhill travel.
It is also important to notice where vents are placed on the helmet. Vents that are closer to the brow offer convenient cooling while chin guard vents allow them to breathe easier and better. Internal airflow channels work by drawing in air and making sure it circulates inside the head to keep it cool.

6. Safety Standards

The full-face MTB helmets are used for more aggressive MTB riding such as downhill riding as they are safer and protect the head more. All MTB helmets must meet the minimum safety standards (CE EN 1078). Many full-face helmets come with thicker cores and long-lasting shells with enhanced safety features – dual density cores and MIPS. Some full-face MTB helmets meet the international ASTM standards for DH.

7. Removable chin guards

Enduro style full-face helmets are sometimes equipped with removable chin guards. This chin piece can be taken off for extra ventilation and ease of breathing when climbing uphill. Removable chin guards are less protective than fixed chin bars. A few full-face helmets that come with removable chin bars meet the ASTM DH certification.

8. Construction

In-mold PC: Here, the shell and the EPS liner are fused using pressure, heat, and steam to form the perfect shape in a vacuum before the in-mold process. In-mold construction will allow the helmet to maintain a low weight and provide sufficient protection due to the fused material. In case of a crash, impact forces will be distributed over a wider area of the skull so that risk of damage is minimized.

    • Carbontech In-mold: This In-mold production process uses a similar molding process like polycarbonate, but uses carbon to fuse with the shell instead. They are perfect for helmets that are designed with larger vents.
    • Glued: The Shell and EPS are joined together using glue to give us the final product. The shell protects the EPS liner here.
    • Hardshell: Injection molded ABS or PC outer shells are joined together with the EPS inner lining. The PC/ABS-material offers very good protection as it is a solid and strong material. Hard shells are most effective against outside impacts and can also offer full cover protection.

9. Visor

All full face mountain bike helmets come with a visor that will keep the sun or rain away from the rider’s eyes. Adjustable visors can be put away when not required so that vision is not obstructed.

10. Goggle Compatibility

Full face mountain bike helmets have a design that is compatible with goggles. However, some goggles may work better due to their different shapes. Some full-face helmets are compatible with googles from specific brands.

11. Action camera mounts

A dedicated action camera mount will allow riders to attach their GoPro securely to their full face MTB helmets. Break-away mounts will eject the camera in case of a crash. They are considered to be very safe and reliable.

How to find the proper helmet size

  • Get hold of a fabric or paper tape measure if possible.
  • Essentially measure around the widest (biggest circumference) part of your head and the most prominent portion at the back of your head.
  • Note down the measurement in centimeters.
  • All helmets have size ranges and with your head measured it’s then easy enough to find which sizing has your head size covered.
  • Use the picture below as a reference and use the “red line” as the widest part of the head for better measurement :

F. A. Q.s

Q1. Is it necessary to use a mountain bike helmet?

Ans.: As we know, mountain biking involves a lot of off-road cycling, where riders face downhill/uphill stages as well as stages dedicated to enduro racing. Therefore, riders want to select the helmets that will provide the best safety and protection over other features such as aerodynamic design/shape, strong material, additional features like camera mount, and of-course easy handling.
MTB helmets are usually full-face helmets and the ones that are available these days are light but very safe. Manufacturers have redesigned the traditional MTB helmets to be on the lower weight scale, with sufficient ventilation via strategically placed vents, deep-internal channeling, wider front opening, etc. Usually, MTB helmets feature visors that can be fixed or adjustable. Going a step further, some MTB helmets now have a removable chin bar that will allow you to go open face/full face – whatever suits you the best!

Q2. How often should you replace a helmet?

Ans.: Typically, it is suggested that you replace your helmet after using it for a period of 3 years. The foam padding of your helmet will be worn out after this period due to exposure to sweat, heat, etc – in addition to any other damage incurred to the helmet by crashing.
However, this is not a rule and totally depends on how you feel about your helmet and how often you use it. Look out for signs like cracks that may have formed on the foam, condition of the inner lining, shell, and so on. Manufacturers also look to upgrade on features like padding, protection technology, fit, etc on many existing models and you can look for a similar replacement. If you are involved in a crash that has compromised the inner foam, it is a good idea to look for a new one as the helmet might not be able to offer you the same protection if you get into an accident again in the future.

Q3. MIPS and other anti-rotational features of an MTB helmet?

Ans.: Anti-rotational features of an MTB helmet are explored below:

  • MIPS: MIPS helmets are built with an internal layer of plastic and other components such as stretchy fabric. During a crash, that layer helps keep the brain from absorbing all the rotational force that is created at the moment of impact.

MIPS

  • SPIN: A silicone gel-like membrane into the pads that – in the event of a crash – will ensure that rotational forces are not transferred to the head and allow the EPS shell to rotate independently of the wearer’s head.

SPIN

  • WaveCel: WaveCel is a cellular structure that supplements the traditional EPS shell. It can rotate and shear as it compresses so that it can reduce both linear and rotational forces.

WaveCel

  • LDL(Low-Density Layer): Rotational forces are addressed with Low-Density Layer from Kali, where the layer is made using strips of gel cups. The pads are mounted on top of the strips which compress, rotate, and shear so that both rotational and linear forces are minimized.

Low Density Layer

  • 360° Turbine: An energy-absorbing material is used as implants that can be molded and are disc-shaped. They have been positioned strategically inside the helmet so that it can dissipate rotational forces while directing and deflecting impact energy, which reduces 30% head impact at concussion level. The acceleration will be also reduced to 40% to the head and brain.

360° Turbine

  • ODS (Omni Directional Suspension): Two separate EPS shells have been connected by elastomer dampers to allow the shells to float, rotate and compress independently of each other.

Omni-Directional Suspension

Q4. Why Do Mountain Bike Helmets Have Visors?

Ans.: Mountain bicycle helmets have visors for protection to the face and eyes from branches that hang low over the trails and also shield you from the sun, rain, and mud. They also deviate sand or gravel during cornering.

Q5. Full-face MTB helmets vs Half Shell MTB helmets?

Ans.: We have explored the difference between Full-Face MTB helmets and Half Shell MTB helmets using the table below:

 Full-face mountain bike helmetsHalf-shell mountain bike helmets
Suitable ForBMX, Enduro, and more aggressive Downhill ridersAll-mountain, Trail, and Cross-Country riders
Key Featuresi. Offers full coverage of the head;

ii. Consists face and a chin guard that is usually wrapped around the front of the rider’s helmet
i. Offers protection for the top of the rider’s head and runs down to the backside of the head. The siders finish just before reaching the ears
Prosi. Optimum protection

ii. The rider can stay focused as the helmet cuts out any noise from the surrounding
i. Versatility allows riders to use these helmets for a wide variety of riding styles

ii. More ventilation as the chin bar is completely detached due to the simple put-on/take off
Consi. Usually tend to be heavy

ii. You will need some time to break into these helmets for the perfect fit

iii. The inside may be stuffy for some riders at the beginning
i. Cannot offer the same level of protection as full face MTB so should be avoided on on aggressive risky terrains

Conclusion

MTB riders should use a full-face helmet for maximum safety as the rider can have an accident at any time during mountain riding. If you are a mountain bike rider, then you should find the best full face MTB helmet for you. This will surely not be easy as there are a wide variety of products available with their different features.
