HeatGear® Cooling Technology

The proprietary HeatGear® fabric is engineered to keep your body temperature regulated when the heat is on. Incredibly lightweight yet durable, it wicks sweat rapidly away from your skin and allows it to evaporate quickly so you stay dry and comfortable throughout your entire activity.

Strategic Mesh Ventilation

Mesh panels are positioned at the underarm and across the back — precisely where your body generates the most heat — to channel airflow directly where you need it most. The result is superior breathability that keeps you feeling fresh from the first tee to the 18th hole.

Ergonomic Construction

Every seam is thoughtfully placed away from high-friction zones so you experience no chafing or irritation during extended wear. The hybrid raglan sleeve design integrates seamlessly into the body for a wider, unrestricted range of arm motion — essential for a full, powerful golf swing.

Fitted Silhouette

The fitted cut sits close to the body without feeling restrictive, giving you a clean, athletic profile. This is not compression — it's the ideal middle ground that looks sharp on and off the course while still giving your muscles the freedom to work at full capacity.
