Stay warm and comfortable in cool-weather conditions with the Under Armour ColdGear Infrared EVO Mock-Neck Shirt. Rugged, dual-layer ColdGear EVO fabric - an 87% polyester, 13% elastane blend - combines a slick, fast-drying exterior and an ultra-cozy interior. Four-way stretch fabrication allows greater mobility and maintains its shape longer. The Signature Moisture Transport System wicks sweat away from the body to keep you dry, while antimicrobial technology helps fight odors so you stay fresher longer. The ColdGear Infrared printed interior traps heat for superior warmth without added weight. Smooth flatlock seam construction reduces chafing and allows for easy layering. The low-profile mock-neck collar fits snugly to seal in body heat for even greater warmth. Fitted design. Imported.
