    THE ALTITUDE HELMET FROM 509, IS ONE OF THE BEST SELLING SNOWMOBILE HELMETS ON THE MARKET / The 509 Altitude Helmet is designed and built from the ground up with 4 ideals in mind: Safety, Performance, Fit, & Style. The Altitude Helmet excels across the board.

    PERFORMANCE / Innovative aerodynamic channels run across the entire contour of the helmet. 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.

    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 Altitude is available in 11 sizes from Youth Small to Adult 4X-Large. These 11 sizes are carefully designed across 4 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. The eyeport of the Altitude helmet was carefully crafted to fit our 509 goggles perfectly. The Altitude helmet & 509 brand goggles are two products designed to fit and perform at the highest level when used in combination.

    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 thermoplastic poly alloy material for maximum shell strength with minimal weight.

    STYLE / 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. Each Altitude comes standard with an innovative camera mount, that mounts securely in seconds to the top visor mount.
