Classic Thermal Merino Base Layer Crew – Women's

When winter mornings turn cold on the ridge or in the stand, the Classic Thermal Crew is our go-to base layer for women who stay active in the cold. Merino interlock knit regulates temperature and fights odor naturally, while flatlock seams and a slim fit keep it comfortable under a pack or shell.

• 100% merino wool interlock knit regulates temperature and resists odor naturally, so it stays fresh over multi-day trips
• Thermal weight is warm enough for cold mornings and stand sits, without trapping heat on the climb
• Slim fit layers cleanly under fleece, softshell, or insulated outerwear without bunching or binding
• Flatlock seams reduce chafing under pack straps or a harness, and raglan sleeves keep shoulders moving freely
• Wide range of solid, heather, and printed colorways in sizes XS to XL
