Stage Helmet


Where enduro racing is anything but predictable, Stage is the lightest, most versatile full-face helmet in its class, allowing you to focus on nothing but the terrain ahead. Utilizing three shell sizes constructed of Polylite with fiber reinforcement, Stage combines EPP and EPS for both slow-speed and high-speed protection. The Polylite chinbar features massive openings for ventilation, key for all-day breathability so you can keep charging at the front of the pack.
