Under Armour Thermals: Baselayers for Men & Women

Whether you’re grinding it out in a gym class, crunching the reps, or putting your all in at a match or race, you’re gonna work up a sweat when pushing your limits. Under Armour’s baselayers for men and women give you the gear to smash your goals in - without compromising on comfort and support.

Built using advanced materials and patented technologies, we’ve developed a complete range of baselayer shorts, baselayer leggings, and baselayer t-shirts for men and women. At Under Armour, we don’t do generic, so we’ve tailored our men’s and women’s baselayers to different seasons.

For cold weather training, our ColdGear® dual-layer fabric is designed to provide extra insulation between you and the surrounding environment. That keeps you warm, while still allowing you to wick away sweat and avoid the build-up of perspiration. When exercising on warmer days, we’ve packed our women’s and men’s baselayers with HeatGear® - a fabric which rapidly draws moisture and heat away from the skin. And our Iso-Chill material means our baselayer leggings, shorts and tees feel cool to the touch.

For the most intense workouts, we’ve used UA RUSH™ in many of our compression clothes - minerals in the fabric effectively reflect your body’s heat back at it, encouraging blood flow and faster recovery. We’ve designed women’s and men’s baselayer leggings, shorts, tops and vests with features targeting different sports and workouts.

From men’s baselayer t-shirts for football, to running baselayers for women, compression shorts for the gym or hiking and trail running crew necks, browse the Under Armour thermals collection to find gear that boosts your performance.
