Under Armour HeatGear Comp Mock men's compression long sleeve t-shirt, carbon heather/black

Built for contact-sport athletes who train and compete in the heat, the Under Armour HeatGear® Men's Compression Mock Long Sleeve delivers full arm and neck coverage without weighing you down. Ultra-light HeatGear® fabric lets your skin breathe rather than bake, while a compression fit wraps muscles in a second-skin feel that keeps you locked in and moving freely. Wear it solo as a training top or layer it beneath pads or a jersey – either way, it stays cool, dry and comfortable when temperatures rise.

• Tough, lightweight HeatGear® fabric combines with UA Compression technology for a powerful, second-skin performance fit.
• Stretch-mesh back and side panels provide strategic ventilation to keep air flowing during intense activity.
• Moisture-wicking material pulls sweat away from the skin and dries exceptionally fast.
• Updated ergonomic design keeps seams away from high-abrasion zones, extending the garment's durability.
• Mock neck construction adds extra coverage at the collar for protection during contact sport or layering.
• Versatile enough to wear standalone or as a baselayer under pads or a jersey in hot-weather conditions.

HeatGear® Fabric Technology

The proprietary HeatGear® fabric is engineered specifically for hot conditions. It is ultra-lightweight yet tough, and its moisture-wicking construction transports sweat to the surface where it evaporates rapidly – so you stay cool and dry no matter how hard you push.

Strategic Ventilation

Stretch-mesh panels on the back and sides are precisely placed to maximise airflow exactly where your body generates the most heat. The result is targeted, all-day ventilation without compromising the compression fit or structural integrity of the garment.

Mock Neck Coverage

The mock neck collar provides additional skin coverage at the throat, ideal for athletes who need protection from turf or pads. It sits comfortably against the neck without restricting movement or causing irritation during long training sessions.

Compression Fit

This garment features UA's ultra-tight Compression fit – a second-skin silhouette that hugs and supports the muscles, helping you feel stronger and more powerful with every rep, sprint or tackle. The ergonomic seam placement reduces chafing and extends wear life.
