Ski tours, extended backpacking trips, climbing - this is an exceptionally versatile base layer you’ll go to for anything outdoors. Made from Responsible Wool Standard (RWS) certified Merino, it naturally regulates thermal comfort, resists odours and static, and feels comfortable next to your skin. The fit keeps the wool close to your body for maximum effectiveness, elastane fibres add stretch and hold the fit, and articulated patterning gives you freedom to move.
Crafted at a Fair Trade Certified facility as part of our commitment to transition 80% of Arc’teryx products to fair trade certification by 2025.
