Petzl Altios Climbing Helmet

Strap on the Petzl Altios Helmet for everything from crumbly sport routes to all-day alpine trad outings. This adjustable helmet features a mesh panel and expanded polystyrene liner to give it a weightless feeling. The space created by the line improves ventilation, and the durable ABS shell protects your melon from trundled or loose rock. Dial in the perfect fit with the adjustable chin strap and adjustment wheel, and attach your Petzl Tikka or Zipka with the four headlamp clips.
