ColdGear is the ideal base layer for cold conditions (less than 45 degrees Fahrenheit). It delivers core temperature regualtion and moisture transport via a two-layer fabrication: the soft, brushed inner layer helps lock in heat and repell moisture to the outer layer, where evaporation takes over. Under Armour's versatile Coldgear style can be worn on top of a base layer or as a base layer. The Quarter Zip provides instant ventiallation while maintaining core body warmth in the most extreme conditions.
