Crafts new ZERO Extreme Gore Wind Stop merges three of our most battle hardened fabrics, ZERO, COOL and Gore Wind Stop into the most effective base layer yet. ZERO stays in contact with your body, pulling excess moisture away from your skin, while simultaneously keeping you warm. COOL outer fabric allows air to circulate around your body and further promote moisture expulsion. And for protection from cold and windy conditions, a Gore WS panel is strategically applied to the outer layer of the ZEROextreme fabric to maximize protection where you need it. Antimicrobial treatment to prevent fabric odor from setting in. Guaranteed to be the best fitting, best performing and most comfortable base layer yet.
