The Under Armour HeatGear Men's Compression Long Sleeve Shirt (style #1361524, Carbon Heather) is the original performance base layer — the one you put on first and take off last. Built from ultra-light HeatGear® fabric that wicks sweat away from the skin and dries rapidly, it keeps you cool, fresh, and focused during any activity in warm conditions. The compression fit delivers an ultra-tight, second-skin feel that supports muscles, improves blood circulation, and enhances both performance and recovery. Whether you are running, training in the gym, playing team sports, or using it as an under-layer on the golf course or ice rink, this long-sleeve compression shirt is the versatile performance essential every athlete needs.
HeatGear® — Under Armour's signature fabric engineered for hot conditions (approximately 23 °C–37 °C). It moves sweat away from your body to the surface of the fabric where it evaporates quickly, delivering a noticeably cooler feel even on the hottest days. Moisture Transport System — UA's proprietary wicking technology that continuously pulls moisture away from the skin to the outer surface of the garment so it dries faster and keeps you drier for longer. Anti-Odor Technology — an antimicrobial treatment built into the fabric that inhibits the growth of odor-causing microbes, keeping your shirt fresh session after session.
HeatGear® is Under Armour's original performance base-layer fabric, engineered specifically for warm-weather activity (approximately 23 °C–37 °C). The super-light material delivers superior coverage without weighing you down, wicking sweat rapidly away from the skin to the outer surface of the fabric where it can evaporate quickly. The result is a noticeably cooler, drier sensation even during the most demanding workouts. Unlike heavier fabrics that trap heat, HeatGear® keeps the microclimate between skin and fabric consistently fresh and temperature-regulated, allowing you to stay focused on performance rather than comfort.
Under Armour's Moisture Transport System is a proprietary wicking technology integrated into the HeatGear® fabric that continuously draws perspiration away from the body to the outer surface of the garment. Once moisture reaches the surface, the fabric's fast-drying construction accelerates evaporation, keeping you significantly drier for longer periods than standard cotton or non-treated polyester. This moisture management is essential during high-intensity training or sport — particularly in warm environments — where sweat build-up can cause discomfort, skin irritation, and thermal imbalance. The system works seamlessly with the mesh underarm and back panels to maximise overall breathability.
Under Armour's Anti-Odor technology uses an antimicrobial treatment applied directly to the HeatGear® fabric to prevent the growth of odor-causing microbes at the source. Unlike deodorising sprays or external treatments, this technology is integrated at the yarn level, meaning it remains effective wash after wash and session after session. It is especially valuable for athletes who train frequently and wear their compression gear close to the skin, where sweat and bacteria can cause unpleasant odors rapidly. The technology has no impact on the fabric's feel, stretch, or moisture-wicking performance, making it a seamless hygiene solution built into the garment.
The hybrid raglan sleeve design on the HeatGear® Compression Long Sleeve extends the shoulder seam diagonally from the collar to the underarm rather than across the top of the shoulder. This construction eliminates the restriction that traditional set-in sleeves can create at the shoulder joint, delivering a fuller, unrestricted range of motion for overhead movements, throwing, swinging, and reaching. Combined with the 4-way stretch HeatGear® fabric, the raglan design ensures the shirt moves fluidly with your body in every direction without riding up or bunching. It is an essential feature for athletes across all sports who rely on their upper body for performance.
Strategically positioned mesh panels under the arms and across the back of the shirt provide targeted ventilation precisely where the body generates the most heat during exercise. The mesh knit (92% Polyester / 8% Elastane) allows air to circulate freely through the garment, creating a convective cooling effect that complements the moisture-wicking properties of the main HeatGear® fabric. The ergonomic insets at the sides and lower back simultaneously improve the fit of the shirt, contouring naturally to the body's shape during movement. Together, the mesh panels and the main fabric create a holistic temperature-management system that keeps you cool and dry throughout your session.
The HeatGear® Compression Long Sleeve is cut with an ergonomic seam placement that relocates seams away from high-abrasion contact zones — such as the shoulder cap and underarm — to increase garment durability and eliminate chafing over long periods of wear. The ultra-tight, second-skin compression fit applies consistent pressure to muscles, which is widely used by athletes to enhance blood circulation, reduce muscle oscillation during dynamic movement, and support faster recovery post-exercise. The crew neck is smooth and narrow with the band set directly into the body for added comfort, while the narrow profile under layers seamlessly beneath uniforms, training tops, or outerwear without adding bulk.
