Classic Thermal Merino Base Layer 3/4 Bottom – Women's

Built for cold-weather output on the slopes or winter trails, the Classic Thermal Merino Base Layer 3/4 Bottom is our top pick for women who run hot but still need real warmth. Merino wool interlock knit regulates temperature and resists odor through long days in the cold, while flatlock seams and a 3/4 cut keep things chafe-free and boot-compatible.

• 100% Merino wool delivers natural warmth, breathability, and odor resistance without synthetic funk
• Interlock knit construction adds durability and next-to-skin softness for all-day wear
• 3/4 length sits above the ankle to eliminate bunching inside ski, snowboard, or hiking boots
• Flatlock seam construction reduces chafe during high-output cold-weather activities
• Slim fit and wide elastic waistband layer cleanly under shell pants or bibs without bulk
