Under Armour Boys Cold Gear Mock: Tight muscles restrict your movement and leave you vulnerable to injury. The double-sided fabric of ColdGear disperses heat from the hotter areas of your body throughout the shirt to regulate your core temperature. Combined with Under Armour's signature moisture-wicking capabilities, ColdGear keeps you dry and warm in almost any climate. This Mock features a new brushed fabrication for enhanced thermal protection and superior slip-on feel for added comfort.
