Under Armour HeatGear® Long Sleeve - Green

HeatGear® is Under Armour's original performance baselayer fabric, specifically designed to keep you cool, dry, and light in warm conditions. It wicks sweat away from your body and dries quickly.

It uses super-light HeatGear® fabric to wick sweat rapidly and strategic mesh panels under the arms and on the back to provide targeted ventilation, allowing heat to escape and air to circulate.

While it's designed for warmth, it can be worn as a base layer in cooler conditions. For optimal warmth, you would need to layer it with mid and outer layers designed for cold weather.

Machine wash cold with like colors. Use non-chlorine bleach only when needed. Tumble dry low. Do not iron. Do not use fabric softeners. Do not dry clean.

Fabric softeners can leave a coating on the synthetic fibers, which can clog the fabric's pores and hinder its ability to wick sweat and dry quickly, compromising its performance.

The locker tag on the back of the neck allows you to write your initials or number, which can help with identification, especially if you have multiple similar items or are part of a team.

Yes, its moisture-wicking properties, ventilation, and ergonomic design make it suitable for a wide range of activities, including running, gym workouts, team sports, and other high-intensity training in warm environments.

The HeatGear® long sleeve is designed as a performance baselayer with a snug fit. This compression helps support muscles and wick sweat efficiently. If it feels uncomfortably tight, verify you have the correct size according to Under Armour's sizing chart. A slightly looser fit might be achieved by sizing up, but it may reduce some compression benefits.

Ensure you are following the care instructions precisely, especially avoiding fabric softeners. Fabric softeners can leave a residue that clogs the wicking channels of the material, reducing its effectiveness and potentially trapping odors. Wash promptly after use. For persistent odors, consider using a specialized sports detergent.

Harsh chemicals, high heat, or improper washing can damage the fabric. Always machine wash cold, tumble dry low, and never iron or dry clean. Ensure you are not using chlorine bleach excessively or when not needed, as it can weaken the synthetic fibers.
