When the crag calls and you need a shirt that can handle everything from steep overhangs to dusty approaches, the Arc'teryx SL Cotton Bird Word SS delivers premium performance in a classic package. Built with 100% SUPIMA® cotton, this men's climbing shirt combines the natural breathability and softness you crave with the durability to withstand countless days of rock climbing and bouldering. The articulated patterning and continuous-seam construction work together to give you unrestricted movement whether you're reaching for that next hold or shouldering your pack for the hike out, while the strategically placed shoulder seams ensure comfort under climbing gear and backpack straps. This isn't just another cotton tee - it's climbing-specific design that handles the dirt, sweat, and abuse of serious outdoor adventures while keeping you comfortable when the sun's beating down on the rock.
