Under Armour HeatGear® Short Sleeve - Grey - M

HeatGear® is Under Armour's original base layer technology. It's designed to keep athletes cool, dry, and light. The fabric is super-light and provides superior coverage without weighing you down.

The HeatGear® compression fit is designed to be snug and supportive. It should feel like a second skin. If you are between sizes or prefer a less compressive fit, consider sizing up.

While comfortable, the HeatGear® shirt is optimized for athletic performance. Its technical fabric and compression fit are best suited for sports and training, though some users find it comfortable for casual wear.

This refers to a sleeve design that combines elements of raglan sleeves (sewn from the outer shoulder seam to the underarm) with traditional set-in sleeves. It's engineered to provide a greater range of motion and comfort, particularly for arm movements.

The shirt features mesh panels strategically placed in the underarm and back areas. These panels are made of a more breathable material that allows for increased airflow, helping to regulate body temperature during intense activity.

The main body of the shirt is made from 84% Polyester and 16% Elastane. The mesh ventilation panels are composed of 92% Polyester and 8% Elastane.

Ensure you have selected the correct size. This is a compression fit shirt; if you prefer a looser feel, consider ordering one size up or opting for a different fit type if available.

Check that you are following the recommended washing instructions. Avoid using fabric softeners, as they can clog the fabric's performance fibers. Ensure no bleach residue remains after washing.

Verify the shirt is worn correctly, with seams aligned as intended. For persistent irritation, ensure the garment is not too tight and consider if this specific fit type is suitable for your body and activity.
