509 Altitude 2.0 Helmet

Reinvented to ride even harder, the second generation of the bestselling 509 Altitude series unleashes a whole new animal. Lighter, stronger, and even more comfortable thanks to a new hand lay-up fiberglass construction, the 509 Altitude 2.0 Helmet excels in any terrain or condition. Includes the Fidlock magnetic strap buckle for easy one-handed operation, plus customizable features like a removable Pro-Series Breathbox to get you through a full season of extremes.

Features:

Hand lay-up fiberglass composite construction for stronger, lighterweight, and better fit construction
DOT/ECE certified in USA. ECE available in Canada and Europe
One piece eye port trim
XS to 4X sizes available in three shells for optimal fit and minimal weight
Upper vents with on/off shutter closure for airflow control
Fidlock chinstrap strap closure for easy in and out
Go-Pro mounting capability, improved design
Perfect fit between helmet eyeport and 509 goggles
Pro-Series Breathbox for complete protection, removeable for great air flow
