Icebreaker 260 1/2 zip

A superior base layer in heavyweight merino with ventilation zones for aerobic activities in cold weather, the 260 Zone Long Sleeve Half-Zip is warm, odor-resistant, and incredibly breathable. Body-zoned technology combines a blend of merino wool and LYCRA® with strategically placed merino mesh panels that actively control temperature. The half-zip design allows for easy layering and promotes heat dissipation. Underarm gussets and raglan sleeves increase range of motion. Flatlock seams reduce irritation. Inspired by nature, Icebreaker harnesses the performance qualities of natural fibers and offers an alternative to petrochemical-based synthetic fabric garments. Merino is an annually renewable fiber that naturally resists odor, keeps you cool in warm weather and warm in cool weather; and lets your skin breathe in comfort all day, every day.
