This is the baselayer that you'll never want to take off, that's because while being incredibly comfortable with 100% cotton against your skin, it is also unbelievably warm. That is because it uses UA's patented ColdGear Infrared technology to actually hold heat so the layer warms up faster and stay that way longer. And all without adding any unnecessary weight or bulk. That is because the science is actually built right into the interior coating. Simply put: it is UA's best insulation ever.
