Safety Features MIPS

MIPS is a company that started dabbling in putting together a liner that could help provide extra protection for mountain and downhill bike run riders.

With MIPS, riders get more than just protection from impact taken directly. A helmet always tests very well on direct impact, but that does not always happen with real-world crashes.

Instead, a person’s helmet during a crash usually hits the ground at a bit of an angle, which can create some level of rotational force. With the helmet facing the rotational force, so does the head, putting a person at a pretty big rest.

It is turned into better and better technology, as now MIPS helps solve this problem on a lot of top downhill bike helmets out there right now.

With MIPS implemented, anti-rotational safety is so much better than before. It is extremely important with full face downhill bike helmets, as the chin guard can cause quite a bit of damage during a crash.

If a person hits the ground at the right angle, the helmet can be grabbed from the chin and cause the helmet and head to rotate awkwardly. Without MIPS, it can really put a person at risk.


A traditional mountain bike helmet is going to have two layers. On the outside is a polycarbonate layer that is tough and durable, while the inner layer is made of EPS foam.

The foam is designed to be strong as well, but also comfortable enough for people to wear on their head without feeling too exhausted.

The foam also helps in allowing the helmet to skid a bit, which comes in handy if there is a crash. Otherwise, there is a chance that the helmet would catch and whip a person’s neck around, which is a definite problem in many scenarios.

EPS foam is going to crash and even break if the impact is hard enough. It is capable of absorbing quite a bit of force, but it is much better to see the foam break instead of the head itself.

These two layers work together to help protect as much as possible, so the head injuries are greatly reduced.
