Bi-Ply Crewneck Thermal Top – Women's

When the temperature drops and you need a reliable base layer without the extra bulk, the Bi-Ply Crewneck is our pick for women who run cold or layer hard. Its double-layer spun polyester construction traps a pocket of air between the layers for midweight warmth, while flat-lock seams and a soft, cotton-like feel keep it comfortable against skin all day.

• Double-layer spun polyester traps air between layers for Warmth Factor 7 (midweight) insulation without added bulk
• Moisture-wicking construction pulls sweat away from skin to keep you dry whether you're moving or standing still
• Flat-lock seams eliminate chafe and pressure points — critical when worn directly against skin under a jacket or shell
• Relaxed fit and classic crew neckline layer cleanly under hoodies, fleeces, or ski jackets without bunching
• Available in Black — a versatile base that works under anything and holds up wash after wash
