We took our classic tight fitting Under Armour base layer and re-engineered it for a whole new fit and feel. This performance crew is fitted. That means it's got a next to skin feel without the squeeze of compression. And the new slightly textured fabric feels soft and comfortable next to your skin. The performance though, that's the same old Under Armour you've come to trust. Our Heatgear fabric still keeps you cool, dry, and light. And the built in flat locked seams are smooth, flexible, and deliver 100 percent mobility. We also threw in some UA essentials, like UPF30+ sun protection, and anti-aura technology to keep you as fresh as your moves. In the gym, at practice, or on the trails, the men's Heat Gear fitted short sleeved crew is up for anything.
