This ultra tight, second skin fit top has been engineered with Iso-Chill fabric which helps disperse body heat to make it feel cool to the touch, while the mesh underarm and back panels deliver strategic ventilation. The hybrid raglan sleeve construction provides an added range of motion, while the ergonomic design keeps seams off high abrasion areas and the material also features HeatGear technology to wick moisture away from the skin. 100% Polyester, Machine washable.
