This Under Armour ColdGear Fitted Crew is designed for optimal performance. It features a dual-layer fabric with an ultra-warm, brushed interior and a smooth, fast-drying exterior. Strategic ventilation is provided by stretch-mesh back and underarm panels without sacrificing warmth. The 4-way stretch construction allows for better movement in every direction. The material effectively wicks sweat and dries quickly. An ergonomic design keeps seams off of high abrasion areas for comfort, and the dropped, shaped hem adds to the style. Made from 87% Polyester and 13% Elastane. Care instructions: Machine wash cold with like colors, use only non-chlorine bleach when needed, tumble dry low. Do not iron, do not use softeners, do not dry clean. Style #: 1366068.
