The Altitude 3K helmet meets or exceeds DOT & ECE 2205 safety certification standards. It features an innovative dual density, interlocking EPS foam liner that provides top crash protection in the event of an accident.PERFORMANCE:
Innovative aerodynamic channels run across the entire contour of the helmet. The Altitude 3K helmet features 6 integrated vent scoops that provide necessary ventilation to keep you comfortable when riding. Overall the Altitude features 8 total intake/exhaust vent ports.FIT:
The Altitude was designed with two key fit metrics in mind: Rider fit & Goggle fit. First, we created a custom interior EPS, matched with a premium removable liner. And because fit is only as good as the overall weight, the Altitude starts at a class leading 1120g.STYLE:
We wanted this helmet to not only perform at the highest level, but to look good doing it. The shell features sleek, yet aggressive lines that provide an innovative and unmatched look. Everything - from the integrated front mouth vent, to the innovative ventilation channels, to the sweeping upward-kicked visor - provides a flowing and seamless transition. Each Altitude comes standard with an innovative universal camera mount that mounts securely in seconds to the top visor mount.
