509 Altitude 2.0 Carbon Fiber Helmet
Reinvented to ride even harder, the second generation of the bestselling 509 Altitude series unleashes a whole new animal. Leading the charge is the 509 Altitude 2.0 Carbon Fiber Helmet with a new hand lay-up 3K carbon composite construction that’s lighter, stronger, and straight-up sleeker than anything before it. For those who like to get aggressive, it includes the Fidlock magnetic strap buckle for easy one-handed operation, a built-in universal camera mount, plus airflow control venting.

- Hand lay-up carbon fiber composite construction
- 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 optimal air flow
- 509 helmet bag included
