Classic Thermal Merino Base Layer Women's

Cold days demand a base layer that actually works.

The Women’s Classic Thermal Merino Base Layer Crew delivers serious warmth without bulk. It’s 100% Merino wool — soft next to skin, naturally odour-resistant, and built to regulate temperature whether you’re pushing hard or standing still.

Smartwool updated the fit for better movement, added shoulder panels, and used flatlock seams to cut down on chafing. The result: cleaner lines, better comfort, and a layer you’ll reach for every time the weather turns.

Skiing. Hiking. Winter running. Travel. Everyday cold-weather wear. This one does it all.
