Midweight baselayer bottoms with optimized venting zones for active performance, the Men’s Winter Zone Leggings are our most technical cold-weather leggings. 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. In the gusset we used lightweight, 180gm eyelet merino mesh that actively controls temperature during high-output pursuits, and in the higher-wear areas around the knees we added 230gm merino and polyester waffle jersey for added abrasion resistance. Flatlock seams throughout eliminate chafing during fast-paced days.
Machine wash. Dries fast in the shade, but do not tumble dry. Exact instructions on the care label.
