This multi-outdoor activity half-zip shirt is engineered to trap heat and eliminate moisture, regulating warmth in unpredictable environments. Made from Polartec® Alpha® Direct knit fabric, which actively wicks moisture, dries quickly, and provides thermal insulation and superior breathability during high-intensity activities in cold or damp conditions. Back panels add durability and comfort when wearing a backpack for extended times while hiking or touring. The flatlock seam construction gives you a frictionless experience, and a zip chest pocket keeps your small belongings safe.
Active insulation technology: “Unlike traditional insulation, Polartec® Alpha® is designed to breathe with you – it regulates warmth dynamically as your activity level changes.”
Lightweight & packable: “It provides exceptional warmth without bulk – ideal for layering or solo wear.”
Fast drying & breathable: “No overheating. No sweat accumulation. Just reliable comfort – whether you're skinning uphill or moving through the city.”
Built for movement: “Perfect for high-output activities in cold conditions – alpine touring, fast hiking, or just staying warm on the move.”
