Classic All-Season Merino Base Layer Bottom – Women's

Built for cold-weather runs, early hunts, and all-day trail efforts, the Classic All-Season Merino Bottom is our go-to base layer for women who need versatility across seasons. Merino wool regulates temperature and wicks moisture naturally, keeping you comfortable from sweaty climbs to cold standstills. Available in standard and plus sizes, with a slim fit that layers cleanly under anything.

• Merino wool construction regulates body temperature and manages moisture across a wide range of output levels — from hard efforts to standing still in cold air
• Naturally odor-resistant fibers extend wear between washes, making this a reliable pick for multi-day backcountry trips or back-to-back training days
• Flatlock seam construction eliminates raised edges that cause chafing during high-output activities like trail running, backcountry skiing, or long hiking days
• Slim, low-bulk fit layers cleanly under hiking pants, hunting bottoms, or ski bibs without bunching, restricting movement, or creating pressure points
• Available in standard (XS–XL) and plus sizes (1X–4X) in Black, Light Gray Heather, and Twilight Blue — responsibly sourced merino soft enough for all-day next-to-skin wear
