Under Armour HeatGear® Long Sleeve - Black - M

HeatGear® is Under Armour's original performance baselayer, specifically engineered to keep athletes cool, dry, and light in warm conditions. It rapidly wicks sweat away from the body and dries quickly.

No, this HeatGear® shirt is designed for warm weather or intense activity where cooling is essential. For cold weather conditions, Under Armour offers its ColdGear® line, which provides warmth without bulk.

The HeatGear Compression shirt is designed for an 'Ultratight, second skin fit'. We recommend consulting the Under Armour size chart for accurate measurements. If you are between sizes or prefer a slightly less restrictive feel, you might consider sizing up, but be aware it will still be snug.

While technically possible, this shirt's design and features are optimized for athletic performance. Its compression fit and technical fabric make it ideal for workouts and sports rather than everyday casual wear.

The anti-odor technology is integrated into the fabric. Its effectiveness is long-lasting, especially if you follow the recommended care instructions, particularly avoiding fabric softeners which can build up and diminish its function.

Fabric softeners can leave a coating on the technical fibers of the HeatGear® fabric. This residue can clog the material's pores, reducing its ability to wick moisture, dry quickly, and effectively utilize its anti-odor properties.

The HeatGear Compression fit is intentionally ultratight, designed to provide a second-skin feel for muscle support. If this level of compression is uncomfortable, consider reviewing the sizing chart carefully or exploring Under Armour's other fit options, such as 'Fitted' or 'Loose', for a more relaxed feel.

Ensure you are washing the shirt according to the care instructions. Specifically, avoid using fabric softeners, as they can leave a residue that traps bacteria and hinders the anti-odor technology. Washing with cold water and a good sports detergent can help.

The most common cause for reduced wicking performance is the use of fabric softeners, which can coat the fibers and impair their ability to move moisture. Discontinue using softeners and try washing the garment several times to remove any residue. Also, ensure the shirt is completely clean and not saturated with old sweat or dirt.

While the shirt features an ergonomic design to minimize chafing, individual sensitivity varies. Ensure the shirt fits correctly; an overly tight or loose garment can sometimes cause issues. Make sure the shirt is worn smoothly without bunching. Consider using anti-chafing balm in sensitive areas if irritation persists.
