The Icebreaker Men’s Bodyfitzone Winter Zone midweight baselayer with optimized venting zones for active performance, is a technical base layer for highly active days in cold conditions. Fully functional for warmth, ventilation, and support while alpine climbing, backcountry skiing, or other day-long adventures in the wild. The top features 260 gm merino wool fabric with a touch of LYCRA® for stretch and a deep front zip for easy heat dumping. Lightweight, 180 gm eyelet merino mesh that actively controls temperature during high-output pursuits in the underarm, and in the higher-wear areas around the elbows and forearms is 230 gm merino and polyester waffle jersey for added abrasion resistance. Flatlock seams throughout eliminate chafing during fast-paced days.
