• K2's premium construction for an ultra-lightweight performance features an EPS liner molded directly to a polycarbonate shell. The result is construction so light that you'll forget you're wearing a helmet.
• Passive Channel Venting: Channels on the inside surface of the EPS direct air-flow between your head and the helmet, removing moisture and excess heat for all day comfort.
• Heat Sealed + Molded Earpads liner: Lightweight and low profile earpads that don't muffle sound or trap heat while still providing great protection.
• BOA Fit System 360
• PowFly Helmet Cover: Waterproof breathable cover for Route for added protection against the elements of winter weather
