The Smartwool Merino Base Bottom is a dependable cold-weather foundation layer built for skiing, snowboarding, and active winter use. Made from 100% Merino wool, it naturally regulates temperature while keeping you warm, dry, and comfortable through long days in the mountains.
Designed with a slim, next-to-skin fit, it layers smoothly under ski and snowboard pants without adding bulk. The fabric is breathable and moisture-wicking, helping manage sweat during high-output activity while staying naturally odor-resistant for extended wear. A wide waistband and flatlock seams add comfort by reducing pressure points and chafing.
