Baselayer Tops

ColdGear Infrared technology holds in body heat, without adding weight or bulk. It's a special, soft print on the inside and it keeps you warmer, longer, so you can work out in the bitter cold.

UA Base 2.0 is built for cold weather and high activity levels. It uses a unique pattern that's designed to trap heat without adding bulk. Think long underwear, revamped for today's top athletes.
