UA Extreme ColdGear pants keep warm, dry, and light, even in the nastiest weather. You don't drop your routine just because it's cold out. You power through to get great. And to feel that gain with a little less pain, we created our UA Extreme ColdGear pants. They're built from a suede-like micro-brush fleece for a softer, smoother finish. So make no mistake-- these aren't your dad's pilly old fleece pants. They're Under Armor fleece pants, complete with our signature moisture transport system and an extra stretchy cold gear back panel for superior comfort and mobility. These Extreme ColdGear pants also have a thick, high-loft fleece lining, so you can get out there and go no matter what the day has in store.
