Under Armour Armour HeatGear® Long Sleeve - Blue

HeatGear® is Under Armour's original performance baselayer fabric. It's super-light, designed to keep you cool and dry by wicking sweat away from your skin, making it ideal for warm conditions or intense activity.

Yes, you can absolutely wear it on its own. While it excels as a baselayer, its moisture-wicking and breathable properties make it a comfortable stand-alone top for workouts in moderate to warm temperatures.

Machine wash cold with similar colors. Tumble dry low and remove promptly. Crucially, avoid using bleach or fabric softeners, and do not iron or dry clean, as these can damage the technical properties of the fabric.

The HeatGear® Long Sleeve is primarily designed for warm conditions. For cold weather, it functions best as an effective moisture-wicking baselayer underneath additional insulating layers to help keep you dry and regulate body temperature.

The garment is crafted from 100% Polyester, a durable and high-performing synthetic fiber known for its excellent moisture management and quick-drying characteristics.

Info needed: While many performance fabrics offer some level of UV protection, this specific product description does not explicitly state a UPF rating. It's generally a good practice to use sunscreen when exposed to the sun for extended periods.

The HeatGear® fabric is designed for a close-to-skin fit to maximize its sweat-wicking benefits. If it feels uncomfortably tight, verify you have the correct size by consulting the Under Armour sizing chart. It should allow for full range of motion without feeling constricting.

Ensure the shirt is worn as a baselayer directly against your skin, allowing the fabric to efficiently wick moisture. If layering, ensure your outer layers are also breathable to allow moisture to escape. Proper hydration before and during exercise is also important for body temperature regulation.

Review your laundry practices, especially avoiding fabric softeners and harsh detergents. Ensure the shirt isn't being washed with items that have zippers or rough textures that could cause abrasion. Avoid prolonged contact with abrasive surfaces during wear, such as rough gym equipment.

While the fabric wicks sweat, it doesn't inherently have anti-odor technology. To combat residual odors, try using a sports-specific detergent. You can also pre-soak the garment in a mixture of water and a small amount of white vinegar before washing.
