Just a T-shirt? Loose Gear does everything Heatgear does except it's looser. Designed to be worn under ballistic vests, the Under Armour HeatGear T-Shirt is constructed of the very highest quality micro-fiber to wick moisture away from your skin. The quicker evaporation process helps your body keep cooler and more comfortable under pressure (and the blazing sun).

Even though LooseGear is loose fitting it's still incredibly stretchable for extra comfort during any movement.
