Safety:
The Altitude 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. The front chin area of the helmet is protected by a specially designed expanded polyurethane chin insert that provides front impact protection. The outer shell is made of specially designed carbon fiber for maximum shell strength with minimal weight.

Performance:
In addition to its safety accolades, performance was a key focus during the development process. Innovative aerodynamic channels run across the entire contour of the helmet. These channels are integrated directly into shell and direct adequate air flow into the specially designed vent scoops. The Altitude helmet features 6 integrated vent scoops that provide necessary ventilation to keep you comfortable when riding. Overall, the Altitude features 8 intake/exhaust vent ports. And for those cold days, snap in the included cold weather breath box. The unique aerodynamic visor features a locking-top center mount that holds the visor in place and prevents unwanted visor movement.

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. The Carbon Fiber Altitude is available in 8 sizes from XS to 4XL (Thermoplastic Altitude available in 11 sizes from Youth small to Adult 4XL). These 8 sizes are carefully designed across 3 outer shell molds - our competitors only use 2. This provides a precision fit, while minimizing overall helmet circumference. The neck brace ready, contoured shell base provides a comfortable, yet snug feel when putting the helmet on. When the helmet is fully in place it provides an unmatched comfort fit that prevents unwanted helmet movement. The eyeport of the Altitude helmet was carefully crafted to fit our 509 goggles perfectly, further improving our world famous "509 helmet & goggle combo" fit. The Altitude helmet & 509 brand goggles are two product designed to fit and perform at the highest level when used in combination. And because fit is only as good as the overall weight, the Carbon Fiber Altitude weighs in under 1100g while the Thermoplastic Altitude starts at a class leading 1260g.

Style:
Finally, the always important STYLE FACTOR. 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. Last, but definitely not least, we know you want to show off your riding talent while wearing the Altitude helmet. That's why each Altitude comes standard with an innovative universal camera mount that mounts securely in seconds to the top visor mount.
