Icebreaker · Insulation
This thermal midlayer jacket uses RealFleece™ brushed merino blend to insulate without bulk. TENCEL™ Lyocell adds softness and moisture management. Gusseted underarms enhance mobility, while offset shoulder seams reduce friction under packs. Thumb loops keep sleeves in place, and flatlock seams minimize chafing. Zippered hand pockets secure essentials, and a dipped rear hem increases coverage during activity.
