The Under Armour HeatGear Men's Compression Long Sleeve Shirt (style 1361524) is the original performance base layer — the one you put on first and take off last. Built from super-light HeatGear® fabric, it delivers an ultra-tight, second-skin compression fit that wicks sweat away from your skin, dries exceptionally fast, and keeps you cool even during the most intense training sessions. Whether you are running, playing football, hitting the gym, cycling, or wearing it under hockey gear, this long sleeve compression top is a versatile essential for every sport and every athlete. The compression fit supports your muscles to help you feel more powerful and recover faster, while the ergonomic construction ensures complete freedom of movement throughout every rep, stride, or sprint.
HeatGear® — Under Armour's original performance fabric technology engineered specifically for warm conditions (approximately 23 °C to 37 °C / 73 °F to 99 °F). It moves sweat away from your body to the surface of the fabric where it rapidly evaporates, delivering a pronounced cooling sensation even on the hottest days. Moisture Transport System — UA's signature moisture-management system that continuously channels perspiration away from the skin and onto the outer fabric surface, keeping you drier for longer and preventing the clammy feeling that slows you down. Anti-Odor Technology — an antimicrobial treatment built directly into the knit that inhibits the growth of odor-causing microbes, keeping the shirt fresh wash after wash.
HeatGear® is Under Armour's original and most iconic performance fabric — engineered specifically for warm-weather training in conditions between approximately 23 °C and 37 °C. The ultra-lightweight HeatGear® knit is woven from a 84% polyester and 16% elastane blend that feels almost weightless against the skin while still providing complete, unrestricted coverage. The fabric draws moisture away from the body to the outer surface where it rapidly evaporates, delivering a tangible cooling effect that lets you train harder for longer. Its inherent stretch in all four directions means the fabric moves with you, never against you, maintaining consistent contact and compression at every angle of movement.
Under Armour's Moisture Transport System is a signature wicking technology built directly into the HeatGear® knit structure. As your body heats up and produces sweat, the microscopic channels within the fabric instantly begin transporting moisture from the skin's surface outward to the fabric's exterior. Once on the surface, the large exposed area accelerates evaporation, keeping you drier and more comfortable than standard cotton or even basic synthetics. The combined effect means you experience less discomfort, less skin irritation, and a more consistent body temperature across even the most gruelling intervals or match conditions.
Under Armour's Anti-Odor technology is an antimicrobial treatment woven into the HeatGear® knit itself — not a surface spray that washes out. It works by inhibiting the growth of odor-causing microbes within the fabric, meaning the shirt stays noticeably fresher for longer even after repeated intense use. This is particularly valuable during multi-day sports trips, training camps, or anytime your gear needs to perform session after session without a full wash cycle in between. The technology does not affect breathability, moisture wicking, or the soft hand feel of the fabric in any way.
Heat does not escape evenly from the body — it concentrates in specific zones such as the underarms and the centre of the back, which is why Under Armour engineered perforated mesh inserts precisely in those areas. The underarm mesh panels allow hot, humid air to escape from the body's natural heat pockets during dynamic arm movements, while the lower back mesh panel vents the region that is typically covered and trapped against layers or body armour. Together, these strategically placed ventilation zones work with the HeatGear® wicking fabric to maintain a more balanced, comfortable microclimate against the skin throughout your entire activity.
The hybrid raglan sleeve design is one of the most significant performance differentiators on this shirt. By extending the sleeve seam diagonally from the underarm to the collar rather than across the shoulder, the raglan construction eliminates the restrictive shoulder seam that can limit overhead reach and rotational movement. The seams are additionally moved forward off the peak of the shoulder to the front panel, removing them entirely from the area most likely to experience abrasion during contact sports or from equipment straps. The result is a sleeve that follows your arm's natural arc during throwing, reaching, lifting, or cycling, delivering unrestricted range of motion and superior comfort throughout every movement pattern.
The compression fit of this shirt is engineered to apply consistent, graduated pressure to the major muscle groups of the torso and arms, which supports circulation and can reduce the accumulation of lactic acid during intense effort. The 4-way stretch construction ensures the compression layer stays fully engaged and in contact with the skin at every angle — whether you are crouching, extending, twisting, or sprinting. Unlike rigid compression garments that can feel restrictive during complex movements, the elastane content in this shirt gives it the elasticity to move dynamically with the body while snapping back to its original shape instantly. The smooth crewneck with its narrow, band-set edge sits comfortably under team jerseys, hockey pads, or gym clothing without creating bulk or pressure points.
