Heavyweight men's merino wool baselayer bottoms for highly aerobic days in cold weather, the 260 Zone Leggings feature zoned ventilation panels for active temperature regulation and ample breathability.

Heavyweight baselayer bottoms with optimized fabric zones for active performance, the 260 Zone Leggings are our most technical cold-weather leggings. These warm, breathable and odor-resistant bottoms feature our BodyfitZONE construction, which combines a merino wool and Lycra blend with strategically zoned panels of highly breathable eyelet merino mesh that actively controls temperature during high-output pursuits. In the higher-wear areas around the knees we added a merino and polyester waffle jersey for added abrasion resistance. A gusseted construction allows for unrestricted range of motion, and the brushed elastic waistband and flatlock seams eliminate chafing during fast-paced days.
