Under Armour HeatGear® Long Sleeve - Green

HeatGear® is Under Armour's original performance baselayer fabric, designed to keep you cool, dry, and light. It works by wicking sweat away from your skin to the fabric's surface, where it evaporates quickly, helping to regulate your body temperature.

While HeatGear® is designed to keep you cool and dry in warmer conditions, it can be used as a moisture-wicking base layer under warmer garments for cold weather activities. However, it does not provide insulation on its own.

The product description indicates 'HeatGear® is our original performance baselayer,' which generally implies a snug, athletic fit, but it doesn't specifically state 'compression.' For true compression, look for products explicitly labeled as 'compression fit' or 'Armour Compression'.

Machine wash cold with like colors. Use only non-chlorine bleach when needed. Tumble dry low. Do not iron. Do not use fabric softeners, as they can impair the fabric's wicking ability. Do not dry clean.

With proper care, color fading should be minimal. Always wash with like colors and follow the specific care instructions, especially avoiding harsh chemicals or excessive heat, which can contribute to color degradation.

While many Under Armour performance fabrics offer some level of UV protection, it's not explicitly stated for this specific product variant. For guaranteed UV protection, look for products with 'UPF' (Ultraviolet Protection Factor) ratings in their description.

The write-in locker tag on the back of the neck allows you to personalize your shirt by adding your initials or number. This is particularly useful for athletes or in situations where multiple similar garments might be present.

Ensure you are wearing the shirt directly against your skin as a baselayer for optimal sweat-wicking. Avoid wearing cotton layers underneath, which can absorb moisture and reduce the HeatGear® effect. Also, check if fabric softener was used during washing, as it can hinder moisture transport.

Review care instructions carefully. High heat drying or ironing can damage the elastane fibers. Also, fabric softeners can degrade elastic properties. Always machine wash cold and tumble dry low, and avoid softeners.

Performance fabrics can sometimes retain odors. Try using a sports-specific detergent designed to neutralize odors. Ensure the shirt is completely dry before storing it, and avoid leaving sweaty garments in a gym bag for extended periods.
