Columbia Womens HeavyWeight Crew Neck Long Sleeve Base Layer.

Our innovative bodymapped 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. FEATURES: Fabric: 85% polyester/15% elastane Omni-Heat thermal reflective Omni-Wick advanced evaporation Form fit Antimicrobial 4-way comfort stretch Ergonomic seaming
