Think of the Patagonia Capilene Lightweight Women's Crew as the lightest thermal in the drawer, the one you grab when a heavier baselayer would be too much. It is soft, quick-drying and stretchy, sliding under a fleece or shell without adding warmth you do not want.

Why we like it:

Its best trick is staying odor-free trip after trip thanks to a mint-based treatment worked into the fabric.

Features and Functions:

The 2.3 ounce recycled polyester double knit moves moisture off the skin and dries fast, and HeiQ Mint keeps the fabric smelling clean across several days between washes. Seams are flatlocked to sit smoothly under layers, the yarn is recycled to cut waste, and the top is Fair Trade Certified.

Fit and Sizing:

Expect a trim, feminine cut that follows the body without clinging, and it sizes as expected for most.

Bottom Line:

This is the crew for spring skiing, uphill travel and any day you would rather manage sweat than trap heat. It fits women who want a light, unfussy first layer.
