Just because you have to play in the cold doesn’t mean you have to play cold. 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. ColdGear™ features Under Armour’s® signature moisture transport system. Bundling up while exercising can result in overheating, lack of flexibility and impeded movement. This shirt goes on like a second skin, offering compression and moisture transport to keep your body warm and game tight.
