Under Armour ColdGear Infrared Chrome Running Tights - AW15 Imported ColdGear Infrared - Employs a soft, thermo-conductive inner coating to retain heat and provide comfortable, consistent insulation. EVO ColdGear - Consists of a dual layer material blend, whereby a smooth, fast-drying exterior membrane sheds water quickly and a brushed, insulative interior retains heat and maintains the wearer's temperature. 4-Way Stretch Fabrication - Accommodates a full range of motion, unimpeded comfort and excellent shape retention. Moisture Transport System - Wicks moisture away from the skin and onto the fabric's surface, from which it evaporates, to encourage a cooler, drier environment. Anti-Odour Technology - Eradicates odour carrying bacteria before it has a chance to spread.
