Under Armour HeatGear Fitted Short Sleeve Shirt - White

HeatGear is Under Armour's original base layer technology, designed to keep athletes cool, dry, and light. It's engineered to work hard when you do.

The HeatGear line is primarily designed for warmer conditions or as a base layer. For very cold weather, Under Armour offers ColdGear products.

Refer to the Under Armour sizing chart. This shirt is designed with a fitted cut, so consult the measurements carefully to achieve the intended fit and performance.

Yes, the shirt can be worn on its own, especially in warmer weather or during intense workouts where breathability is key. It also functions effectively as a base layer.

The main body is typically made of 84% polyester and 16% elastane, while mesh panels are usually 92% polyester and 8% elastane, providing a balance of stretch, durability, and breathability.

While white can show stains more readily, the sweat-wicking and fast-drying properties help in managing moisture. Proper washing care is recommended.

The hybrid raglan sleeve construction is designed to provide enhanced comfort and a greater range of motion for your arms, allowing for unrestricted movement during various exercises.

Ensure you have selected the correct size. The HeatGear line is designed for a fitted feel; consider a size up if you prefer a looser fit, though this may impact performance benefits.

Verify that the shirt is washed according to care instructions, avoiding fabric softeners which can impede wicking properties. Ensure the garment is not worn out, as older fibers can lose effectiveness.

The ergonomic design aims to minimize this. Ensure the shirt is oriented correctly and that no debris is caught in the seams. If irritation persists, consider if the fitted nature is suitable for your activity.
