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
- 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, removable for great air flow
