Take a jog outside or layer up for a day on the slopes with the Under Armour Base 2.0 Leggings. These fitted leggings lay right next to the skin without the squeeze, while the 4-way stretch fabrication allows you to move freely in any direction with ease. Constructed of polyester and elastane, these materials are quick drying and thermal in order to trap in body heat. Stay comfortable and cozy in the UA Base 2.0.
