Gear up with the 509 Atmosphere Helmet in the exclusive “Highlighter” limited-edition colorway—designed for snow riders who demand maximum visibility, proven protection and all-day comfort. Built to perform on the trail, this helmet blends advanced safety certifications and ride-ready features in a bold new finish.
Featuring a rugged injection-molded polycarbonate shell and dual-density EPS foam with channel venting, the Atmosphere meets both DOT and ECE 22.06 safety standards for full confidence on the sled. Six intake vents and six exhaust vents regulate airflow and manage moisture to keep you cool, dry and focused whether you're charging hairpins or sprinting flatlands. The removable liners and cheek pads are moisture-wicking and quick-dry, making post-ride cleanups and seasonal care easy.
The “Highlighter” edition doesn't just bring standout style—it keeps the same trusted shell, venting system and fit as the standard model while adding high-visibility coloring for riders who demand to be seen and recognized on the trail. Whether you're launching pillows or winding through timber, this helmet puts your safety first and your style loud.
