Technology in Detail

HeatGear® — Keeps You Cool

HeatGear® is Under Armour's original performance fabric engineered specifically for warm-weather and high-intensity training. The ultra-light material wraps around your body delivering superior coverage without adding unnecessary weight. It actively pulls moisture away from your skin and promotes rapid evaporation so you feel dry and cool even under sustained exertion. Whether you're hitting the gym or heading outside, HeatGear® ensures your comfort is never compromised by heat.

Strategic Mesh Ventilation

Precision-placed mesh panels on the back and under the arms create a ventilation network that channels airflow to the areas your body heats up the most. Rather than relying on a single breathable fabric, these targeted mesh zones provide active cooling exactly where it is needed. The result is a consistent, refreshing feeling throughout even the most demanding training sessions, without compromising the garment's overall structure or fit.

Ergonomic Durability & Hybrid Raglan Sleeves

Every seam on this shirt has been carefully repositioned away from the zones most prone to friction and abrasion during sport. This ergonomic design philosophy means the garment lasts longer and eliminates the discomfort of seam rubbing during repetitive athletic movements. Complementing this, the hybrid raglan sleeve construction frees the shoulder joint for a full, unrestricted range of motion — ideal for overhead movements, throwing, or any dynamic upper-body exercise. Together, these two engineering choices make the shirt as durable as it is comfortable.

Fast-Drying Moisture Management

The advanced wicking technology built into the HeatGear® fabric draws perspiration from your skin to the outer surface of the material, where it disperses and evaporates rapidly. This fast-drying action prevents the clammy, heavy feeling that slows athletes down and helps regulate body temperature during sustained effort. Whether you're finishing a long run or pushing through a final training circuit, the fabric recovers its dry, lightweight feel quickly so you can keep performing at your peak.
