The Icebreaker Merino 200 ZoneKnit Long Sleeve Base Layer Top is a high-performance men's base layer designed for active pursuits in cold to moderate conditions. Crafted from a blend of 70% Merino Wool, 27% Nylon, and 3% LYCRA®, this top offers exceptional warmth, breathability, and stretch. The ZoneKnit™ body mapping technology incorporates engineered mesh panels to enhance ventilation where you need it most, while the Corespun fabric ensures durability and a soft, non-itchy feel against the skin.
