HeatGear® Fabric Technology

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.

Strategic Mesh Ventilation

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.

Compression Fit

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.

Hybrid Raglan Sleeve

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.
