Under Armour ColdGear long sleeve mock tops feature two layers of material that create a thermal base layer to keep your body protected from the cold. Moisture management properties are inbuilt to ensure that this long sleeved mock neck shirt is comfortable into the bargain. Perspiration is moved away from the body as heat is retained, making the Under Armour ColdGear mock an item of compression clothing that works as hard as you do. The Under Armour long sleeve mock is a compression fit base layer which means that it fits you closely and provides extra muscle support and enhances circulation. Throw in UV protection and anti odour qualities and you have a long sleeved performance top that is designed to deliver in the cold weather.
