The Smartwool Women’s Classic Thermal Merino Base Layer Bottom is a warm, breathable foundation layer built for cold-weather comfort. Made from 100% Merino wool, it naturally helps regulate body temperature, manage moisture and resist odour, making it an excellent choice for skiing, snowshoeing, winter hiking and everyday layering.

The interlock Merino knit feels soft against the skin while providing dependable warmth without unnecessary bulk. Flatlock seams are designed to reduce chafing during active use, and the Merino-covered elastic waistband adds comfort for long days outside.

An updated slim fit improves mobility and creates a smooth profile under ski pants, hiking pants or everyday winter clothing. The mid-rise waist sits at or just below the belly button for comfortable coverage and easy layering.

Warm, versatile and naturally performance-driven, the Women’s Classic Thermal Merino Bottom is a dependable base layer for anyone spending time outside in cold conditions.
