Description

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
  • Go-Pro® mounting capability, improved design
  • Fidlock® chinstrap strap closure for easy in and out
  • Perfect fit between helmet eyeport and 509 goggles
  • Pro-Series Breathbox for complete protection, removeable for great air flow
