Under Armour HeatGear Long Sleeve Top - White - XS

HeatGear technology is Under Armour's signature fabric designed to keep athletes cool, dry, and light. It's engineered to pull sweat away from the skin and accelerate evaporation, making it ideal for warm conditions or intense training.

Machine wash cold with like colors. Only use non-chlorine bleach when needed. Tumble dry low. Do not iron, do not use fabric softeners, and do not dry clean. Following these steps will help maintain the fabric's integrity and performance.

Yes, its versatile design, sweat-wicking properties, and freedom of movement make it suitable for a wide range of activities, including running, weightlifting, team sports, and general fitness training, serving as an excellent base layer.

This refers to a snug, body-hugging fit that provides a supportive feel. While not a true medical compression garment, it offers a close fit that many athletes find beneficial for muscle support and reducing distraction during movement.

You can wear it comfortably as a stand-alone top, especially in warmer weather or during indoor workouts. Its functional design and aesthetic make it suitable for both purposes.

Yes, the fabric incorporates antibacterial technology designed to prevent the growth of odor-causing microbes, helping you stay fresh during and after your workouts.

The body of the top is made of 84% Polyester and 16% Elastane. The mesh panels consist of 92% Polyester and 8% Elastane, offering a balance of durability, stretch, and breathability.

It is recommended to consult the Under Armour size guide for accurate measurements. Keep in mind that a compression fit is designed to be snug, so if you prefer a slightly less restrictive feel, you might consider sizing up, though this could affect the intended supportive benefits.

While designed for a compression-accentuated fit that supports muscles, ensure you have selected the correct size. If it feels overly tight and hinders your range of motion significantly, consider checking the Under Armour size guide or trying a larger size if you prefer a less restrictive feel.

Verify that you are following the care instructions correctly, especially avoiding fabric softeners, which can impede the wicking performance. Also, consider the external conditions and your activity level; in extremely hot or humid environments, or during very intense workouts, the fabric works optimally but has limits. Ensure you are well-hydrated.

The top features antibacterial technology, but persistent odor can occur. Ensure you wash the top promptly after use. If odors persist, try pre-soaking in a solution of white vinegar and water (1 part vinegar to 4 parts water) before washing, and avoid using excess detergent, which can leave residue.

Review the care instructions to ensure you are not ironing, using fabric softeners, or tumble drying on high heat. These actions can degrade the polyester and elastane fibers, leading to reduced elasticity and fabric damage.
