The Men’s Thermal Base Layer Pants are built for warmth and comfort during cool-weather sailing. Made from grid fleece with a moisture-wicking finish, they efficiently trap heat while keeping you dry. The 4-way stretch fabric, elasticated waistband and gusseted crotch provide freedom of movement, and flatlock seams reduce chafing for all-day comfort. Reinforced with a double layer of fabric over the knees and seat, these pants deliver added durability and protection in high-wear areas. Stretch jersey cuffs reduce bulk at the ankles and help prevent water ingress. These pants are designed for effective layering under technical outerwear.
