661 Evo AM Helmet

The Evo All-Mountain Helmet from 661 is a state-of-the-art open face helmet featuring Boa’s built-in 360° micro-adjustment system. This feature allows the helmet to fit every head shape.

Comfort and Security

Comfort and security was 661’s focus when constructing this helmet, with the spotlight on being able to produce a helmet that only needs adjusting once before you start cycling and then forgotten about.

Remarkable Comfort

661’s Evo AM Helmet is able to reach remarkable levels of comfort due to the padded surface and its 15 vents. You can instantly feel the difference once you try on the helmet with its magnetic Fidlock® closure. With regards to protection, 661 replaced the traditional EPS foam liner with Contego foam due to its superior impact absorption qualities.
