HeatGear® Technology — Stay Cool

Under Armour's HeatGear® fabric is engineered specifically for hot-weather performance. Its tight, moisture-wicking construction pulls sweat away from the skin and expels it rapidly, so you stay feeling light, dry, and comfortable no matter how intense the session gets.

Locked-In Compression Fit

The ultra-tight, second-skin compression fit grips your muscles to help you feel more powerful and focused. The fit doesn't shift even through explosive movements, making this shirt ideal as a standalone training top or as a base layer beneath pads and jerseys.

Freedom of Movement

The hybrid raglan sleeve construction eliminates shoulder restrictions, giving you a full, unrestricted range of motion. Combined with strategically placed mesh panels under the arms and across the back, this shirt keeps air flowing exactly where you need it most.

Versatile Baselayer Coverage

Designed for hot-weather training and as a baselayer under football or lacrosse pads, this shirt excels across multiple sports. Its ergonomic seam design keeps stitching away from high-abrasion zones, ensuring lasting durability whether you're training solo or suiting up for competition.
