Engineered for athletes who push their limits in the heat, the Under Armour HeatGear Men's Compression Short Sleeve baselayer keeps you feeling cooler and lighter even in the most demanding hot-weather conditions. Its ultra-tight, second-skin compression fit locks onto your muscles for a performance-boosting feel, whether worn solo during training or layered under pads and jerseys for team sports. The super-light HeatGear® fabric wicks moisture rapidly and dries fast, so you stay focused on performance — not discomfort. A versatile essential for running, lifting, team sports, and hot-weather baselayer wear.
The proprietary HeatGear® fabric is engineered to be ultra-lightweight while still delivering full-body coverage. It moves moisture away from your skin to the fabric surface where it evaporates quickly, keeping your body temperature regulated during intense hot-weather activity.
Mesh panels positioned at the underarm and back zones create targeted airflow exactly where your body generates the most heat. This intelligent placement enhances breathability without compromising the garment's structural compression support.
The ultra-tight, second-skin compression fit gently squeezes your muscles to promote a feeling of power and reduce muscle oscillation during movement. If you prefer a less compressive feel, Under Armour recommends sizing up one size.

The hybrid raglan sleeve construction is designed to eliminate restrictions at the shoulder joint, giving you a wider and more natural range of motion. Paired with the ergonomic seam design, the shirt moves with your body rather than against it — ideal for overhead lifting, running, and dynamic sport movements.
