The outer shell is made of 4 types of polycarbonate for optimal protection. We also noted the precise fit of this helmet: with the Occigrip system, it stays securely in place on the head.
Obviously, the Trailblazer MIPS offers excellent breathability thanks to its Digitally Optimized Ventilation System (DOV).

How to Choose a Mountain Biking Helmet
One of the most important things to consider when buying a mountain bike helmet is its ability to protect. We evaluated six different helmets, some with very innovative safety mechanisms and others based on traditional construction. Choose a helmet that meets your needs based on where you plan to ride and what kind of riding you plan on doing.
Mountain bike helmets have two main components: the shell and the interior construction. The outside shell is normally made of polycarbonate plastic while the inside is often made of EPS foam. The exterior of a mountain bike helmet should be slightly harder than that of a road bike. Pay special attention to the thickness of the outer layer for maximum protection.
How to tell if the helmet is properly adjusted
The helmet should always fit snug and that’s why the six models that we presented to you have precise adjustment systems. A helmet that moves over your head while riding will be likely to cause damage in the event of a fall or collision.
It’s best to opt for a helmet that offers increased protection on the sides and back of the head. If you fall on a bike path, these are the parts of the head that are most likely to be impacted.
Several mountain biking helmets have MIPS and SPIN technologies, both proven to significantly reduce the risk of brain damage. The outer shell is separated from the inner layer and pivots to absorb the shock in the event of a collision.
Always take ventilation into account when shopping for a mountain bike helmet – especially when cross country riding. The best way to assess the ventilation of a helmet is with its openings on the top. Our best choice, the Smith Optics Forefront 2 MIPS has more than one.
The most important features in mountain biking helmets are ventilation, the weight of the helmet (which should be light) and protection. If your budget allows, choose a helmet with MIPS or SPIN technologies. It will give you increased protection in the event of a fall.
FAQ FOR MOUNTAIN BIKING HELMETS
Why do mountain biking helmets have visors?
The visor protects your eyes and face from the sun, but also from debris such as sand, dust, and branches.
How often should I change my mountain bike helmet?
A bicycle helmet does not have an expiration date, but it should be replaced after 5 to 10 years of use. It will also lose its effectiveness after any collisions or damage.
Can I use my mountain bike helmet for road cycling?
Mountain bike helmets have a visor while road bike helmets usually do not. The body position on a road bike is more advanced than on a mountain bike, so the visor may obstruct vision. For this reason, we recommend choosing a helmet for its specific use.
How are mountain bike helmets evaluated?
Downhill helmets go through rigorous testing on several types of terrain and trails.
We hope our buying guide makes it easier to choose one of the best mountain bike helmets for you. There are no specific rules to follow when shopping for a mountain bike helmet. Instead, choose one that has been designed specifically for your riding style and that fits your budget! If you’re still stumped, we recommend checking out our top choice, the Smith Optics Forefront 2 Helmet, which has superior technology and protection.
