It offers performance stretch, effective thermal regulation, and has an excellent feel next to the skin. The fabric is treated with Polygiene® odour controlling finish that helps keep it fresh during repeated use and washings. The women’s specific design optimizes the next to skin fit, articulated patterning and gusseted underarms add freedom of movement, flatlock seams minimize irritation, the tall collar seals in warmth, and the deep zip neck opens easily for rapid ventilation.
