The Silex Cap is built for rocky approaches where low weight cannot come at the expense of toughness. Abrasion-resistant nylon and a water-shedding finish handle brushes with branches, while the fast-drying Spacermesh™ band manages sweat on steep climbs. A button-free crown sits comfortably beneath a helmet, and the rounded brim stays out of the way when you look up. From crag to trail to mountain town, Arc'teryx gives this climbing cap technical purpose without visual clutter.
