Classic Thermal Merino Base Layer Crew – Women's

Built for cold-weather layering in plus sizes, this crew is our top pick for women who need a reliable thermal base that actually fits and moves. 100% Merino wool regulates temperature and manages moisture naturally, so you stay dry and warm without synthetic fabrics. Flatlock seams and a plus-specific cut mean no bunching or chafing under a shell or mid-layer.

• 100% Merino wool construction delivers natural warmth, breathability, and odor resistance across long days in cold conditions
• Interlock knit build adds durability and a soft next-to-skin feel that holds up through repeated washes and hard use
• Plus-size specific pattern — not just scaled up — moves with your body and layers cleanly under outerwear without bunching
• Flatlock seams run flat against the skin to prevent chafing and hotspots during high-output activity
• Available in sizes 1X–4X and multiple colorways including Black, Charcoal Heather, Dark Teal Heather, Twilight Blue Heather, and Light Gray Color Shift
