Under Armour HeatGear® Long Sleeve - Blue

HeatGear® is Under Armour's original performance baselayer fabric. It's super-light and designed to deliver superior coverage without weighing you down. Its primary function is to wick sweat away from your body and dry very quickly, helping you stay cool, dry, and light in warm conditions or during intense activity.

The HeatGear® Long Sleeve is primarily designed for warmth and comfort in warmer temperatures or as a baselayer during intense, heat-generating activities. While it provides a foundational layer, for very cold weather, it should be paired with additional insulating layers, such as a cold-weather fleece or jacket.

For best results, machine wash cold with like colors. Tumble dry low. Avoid using fabric softeners, bleach, or dry cleaning, as these can damage the fabric's wicking properties and overall integrity. Do not iron.

This garment is designed as a performance baselayer, which typically means a snug, close-to-body fit. This fit is essential for effective sweat-wicking and allows the fabric's four-way stretch and ergonomic design to function optimally, providing superior coverage and comfort without constriction.

Absolutely! The HeatGear® Long Sleeve is incredibly versatile. Its moisture-wicking, quick-drying, and flexible properties make it ideal for a wide range of activities including running, cycling, team sports (like football or basketball), hiking, and even as a comfortable everyday layer for active lifestyles.

Info needed: While many performance fabrics offer some level of UV protection, this specific product description does not explicitly state a UPF rating. For sun protection, it's always best to combine with dedicated UPF apparel or sunscreen if prolonged sun exposure is expected.

The HeatGear® Long Sleeve is designed as a performance baselayer with a close fit for optimal wicking. If it feels uncomfortably restrictive, verify you selected the correct size. Refer to the Under Armour size chart for an accurate fit. Ensure the hybrid raglan sleeves and four-way stretch are not being inhibited by incorrect layering.

Ensure the garment is clean, as residue from fabric softeners can impair wicking performance. Always machine wash cold and tumble dry low without fabric softener. For very intense activities, consider if your outer layers are also breathable enough to allow moisture to escape.

While the ergonomic design reduces seam friction, prolonged contact with very rough surfaces or excessive rubbing from backpacks/gear can still cause wear. Always follow care instructions to maintain fabric integrity. Avoid washing with items that have zippers or velcro that could snag the fabric.
