509 once again raises the bar with the new 509 Altitude Snowmobile Helmet! This all new 509 helmet is the result of desire to create and innovate the industry’s best snowmobile helmet. The result is a helmet that is designed and built from the ground up with 4 ideals in mind: safety, performance, fit and style. Featuring an innovative dual density interlocking EPS foam liner the Altitude helmet provides top crash protection and is certified to meet or exceed DOT and ECE 2205 safety standards. These high safety standards were achieved by the use of a specially designed thermoplastic poly alloy shell that offers maximum strength and minimal weight. To protect the rider from a front impact the Altitude uses a specially designed expanded polyurethane insert in the chin area. SAFETY STANDARDS – DOT & ECE 2205 CERTIFIED! Safety is 509’s #1 focus when designing their helmets. With the development of the new Altitude helmet 509 put an emphasis on safety & quality. First is the dual density internal EPS foam. This provides two innovative levels of crash absorbing protection. Next 509’s industry leading thermoplastic poly alloy outer shell that provides a high level of puncture prevention. The 509 Altitude helmet is covered by not one, but two world leading safety standards: DOT & ECE 2205 Certification. Most competitors only offer one level of safety certification.
