The Smartwool Men's Intraknit Thermal Merino Base Layer Crew is a lightweight merino wool first layer built for cold-weather, high-output activity. Its Intraknit construction knits insulation, ventilation and stretch zones into one seamless piece, with gender-specific vent placement for men. It suits skiers, winter runners and mountaineers who want warmth without bulk. Against heavier merino crews it trades some warmth for breathability and freedom of movement; against synthetic base layers it offers better odor resistance and a softer feel, at a higher cost and with more careful washing needed.
