SixSixOne 661 Evo AM TRES MTB Mountain Bike Cycling Helmet

The EVO AM (All Mountain) Helmet. As the name implies, the Six Six One Evo AM Helmet is a next generation trail helmet with all the features you need. The modern-looking shell is built from Contigo foam, which was chosen for its energy-absorbing properties.
Specifically, it's claimed to absorb as much as 30% more energy from an impact than the EPS foams used in almost every other certified bicycle helmet. While that may be the most important detail, more subtle refinements, such as the two-position adjustable visor and the user-friendly Boa retention system mean that you don't have to forgo modern features in the pursuit of protection.
And it's topped off with a Fidlock magnetic buckle that takes pretty much all the effort out of strapping on your lid, despite the fact that it's completely secure.
