Men’s Baselayer Comfort

Stay focused no matter what the weather with men’s baselayer clothing from Under Armour. Take your game-day gear to the next level with our men’s leggings, shorts, tank tops, and undershirts. Whether you’re honing your skills or showing them off, our baselayers help you stay mobile and comfortable so you can work on performance. Our men’s baselayer shirts are built for all sports, like tight tanks in lightweight material that helps wick sweat away from your skin.

Hit the slopes with ColdGear® leggings. You’ll stay warm and dry and can keep going all season long. Pair them with a mock turtleneck for even more coverage when the wind whips and the temperature drops.

Hit the track and crush those PRs in men’s performance thermals that stretch with you to keep you moving toward your goals. Their four-way stretch material is always prepared for explosive action.

Need premium defense on the gridiron? Pick up our baselayer bottoms for football. In addition to the benefits of our traditional men’s tights like mesh panels, sweat-wicking material, and smooth compression, they also have molded pads on the thighs, hips, and tailbone for added protection.
