Redefine your ride with the 509 Altitude 2.0 Helmet in the exclusive “Highlighter” limited-edition colorway—designed for high-speed trail runs, mountain missions and full-throttle sled days. Lighter, stronger and more versatile than the previous generation, this helmet delivers pro-grade performance every time.
Built with a hand-lay-up fiberglass composite shell for optimal strength and weight, the Altitude 2.0 comes equipped with a Fidlock® magnetic chin strap for fast one-handed operation, a removable breath box for use in extreme cold, and a one-piece eye port that seals flawlessly with compatible 509 goggles.
The Highlighter edition retains the core tech of the Altitude series while offering high-visibility graphics that demand attention on and off the mountain. Whether you're launching pillows, threading trees or cruising tunnel roads, you'll ride safe and stand out.
