When the crag calls and you need a shirt that can handle everything from technical face climbs to multi-pitch adventures, the Arc'teryx Kragg SL Cotton Bird Word Short Sleeve delivers premium performance wrapped in luxurious comfort. Built with 160gsm SUPIMA cotton that's naturally breathable and incredibly durable, this climbing shirt moves with you through every reach, mantle, and heel hook while keeping you cool when the sun beats down on exposed rock. The continuous-seam construction eliminates hot spots during long climbing sessions, while dynamically placed shoulder seams work seamlessly under pack straps and harnesses. Whether you're working a challenging boulder problem or hiking into remote climbing areas, the Kragg's articulated patterning ensures unrestricted movement so you can focus on the route ahead, not your gear holding you back.
