The Under Armour Coldgear Armour Legging is built for those of us who don't let the cold keep us cooped up inside and who push ourselves in frigid temperatures to make sure we're hitting our daily and weekly goals. The dual-layer material provides comfortable warmth as the mercury drops and stretch-mesh panels offer strategic ventilation, so we stay comfortable on the move. The stretchy, moisture-wicking fabric is designed to fit like a second skin, offering total freedom of movement so we can push through the final mile of our run without ever realizing it's there.
