The Smartwool Women’s Classic Thermal Merino Base Layer Crew is a warm, breathable first layer built for cold-weather adventures. Made from 100% Merino wool, it naturally helps regulate body temperature, manage moisture and resist odour, keeping you comfortable through changing conditions and active days outside.

The soft interlock Merino knit provides dependable warmth without excessive bulk, making it ideal for skiing, winter hiking, climbing, biking and everyday cold-weather layering. Flatlock seam construction helps reduce chafing, while raglan sleeves and shoulder panels improve comfort and freedom of movement.

An updated fit is designed to work comfortably across a wider range of body shapes, while the back body seam wraps toward the front for a more contoured fit. The classic crew neck layers easily under insulated jackets, shells and midlayers.

Warm, soft and naturally performance-driven, the Women’s Classic Thermal Merino Base Layer Crew is a dependable foundation for staying comfortable in cold conditions.
