Crag Sender Climbing Helmet

Mammut's Crag Sender Collection consists of climbing gear specialized for modern climbing at sport crags, and the Crag Sender Climbing Helmet is lighter and more performance-oriented than most of Mammut's helmets for all-around climbing. It utilizes a hard shell for lightness and reliable durability, and EPS foam adds impact protection. You can adjust the fit with a dial that's easy to use even while climbing, and there's an adjustable chin strap and additional cushioning to ensure a snug fit.
