661 Evo AM Helmet with MIPS

The ultimate All-Mountain open face helmet with built-in 360 degree BOA micro-adjustment to fit every head shape. When developing our EVO AM helmet, we focused on comfort and security.
The goal was to deliver a helmet that you only need to adjust once when starting your ride and then forget about it. The 3 shell sizes (XS-S, M-L, XL-XXL), our BOA 360 micro-adjustment, the padding surface, and its 15 vents all allow the Evo AM to reach an impressive level of comfort. Combined with a magnetic Fidlock closure, we know you will immediately feel the difference as soon as you try one on.

On the protective side, we pushed the envelope by replacing the traditional EPS foam liner with CONTEGO foam, which provides superior impact absorption characteristics. Add to this the MIPS option we offer in all color ways, the Evo AM provides you with best in class technologies.
