We just raised the snowmobile helmet game to new heights. Or shall we say to a higher ALTITUDE. Introducing the all new Altitude snowmobile helmet from 509. The Altitude helmet is the result of a fearless desire to not only create, but innovate. It is the product of looking at every feature of our previous Evolution helmet and asking the tough question, “How can we improve?”. The result is a helmet designed and built from the ground up with 4 ideals in mind: Safety, Performance, Fit, & Style. The Altitude helmet excels across the board.
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 a specially designed thermoplastic poly alloy material for maximum shell strength with minimal
In addition to it’s 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 into the special thermoplastic poly alloy 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 total
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.
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 Altitude is available in 9 sizes
from Youth Small to Adult 2XL. These 9 sizes are carefully designed across 3 outer shell molds,
when 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 excessive helmet movement. The eyeport of the Altitude helmet was
carefully crafted to fit our 509 Sinister X5 & Aviator goggles perfectly. Not only continuing, but
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 Altitude starts at a class leading 1260g.
Finally, the always important STYLE FACTOR. We wanted this helmet to not only perform at the highest levels, but 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 GoPro® camera mount, that mounts securely in seconds to the top visor mount.
