A midweight baselayer zip shirt with optimized venting zones for active performance, the Men’s Winter Zone Long Sleeve Half Zip from Icebreaker is a technical top 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 body features 260gm merino wool fabric with a touch of LYCRA® for stretch and a deep front zip for easy heat dumping.
In the underarm panels we used lightweight, 180gm eyelet merino mesh that actively controls temperature during high-output pursuits, and in the higher-wear areas around the elbows and forearms, we added 230gm merino and polyester waffle jersey for added abrasion resistance.
Flatlock seams throughout eliminate chafing during fast-paced days.
