Developed with top physiologists, Columbia’s new heavyweight base layers offer our highest warmth-to-weight ratio for optimal comfort in extreme winter conditions.
Our innovative body mapped design keeps you warm and dry by placing Omni-Heat® reflective dots in zones that need warmth most, and Omni-Wick™ in high-perspiration zones for maximum moisture transmission. Supple fabric has a soft, sueded hand and an antimicrobial treatment to keep it feeling (and smelling) fresh during high-exertion activities. Highly stretchable, with flat-lock stitching to avoid chafing and raglan sleeves for extended range of motion, this is the heavyweight champion of cold-weather comfort.
