The Under Armour ColdGear® Compression Mock is the original cold-weather baselayer engineered to keep you warm, dry, and focused when temperatures drop. Built from Under Armour’s signature dual-layer ColdGear® fabric, this men’s compression top traps heat against your body with an ultra-warm brushed interior while a smooth, fast-drying exterior keeps you comfortable during any activity. The ultra-tight, second-skin compression fit supports your muscles without restricting movement, making it ideal as a standalone training layer or as a performance baselayer under a midlayer or jacket.
At the core of this top is Under Armour’s signature ColdGear® dual-layer construction. The brushed interior works like an insulating barrier, trapping warm air close to your body even in freezing conditions. The smooth outer face repels moisture and dries at speed, so you never feel damp or weighed down. Together, these two layers deliver the warmth of traditional cold-weather gear in a fabric that is remarkably thin and non-bulky — perfect for layering under a polo shirt, sweater, or jacket without restricting your movement.
Even in cold weather, hard effort generates heat and sweat. Under Armour addresses this with strategically placed stretch-mesh panels at the back and underarms, providing targeted ventilation exactly where your body produces the most heat. The open-knit mesh allows hot air to escape during peak exertion, preventing overheating, while the surrounding ColdGear® fabric maintains insulation everywhere else. The result is an active thermal balance that adapts to your effort level rather than simply trapping heat uniformly.
The 87% polyester and 13% elastane fabric blend enables true 4-way stretch, meaning the material flexes and recovers in all four directions — horizontally, vertically, and diagonally. Whether you are swinging a golf club, sprinting on the pitch, or executing a deep squat in the gym, the top moves with your body rather than against it. This unrestricted range of motion also means the compression fit never pulls, bunches, or restricts circulation, delivering a locked-in second-skin feel across the full spectrum of athletic movement.
ColdGear® is not just about warmth — it is equally engineered for moisture control. The fabric actively wicks sweat away from your skin and transports it to the outer face of the garment, where it disperses and evaporates quickly. This continuous moisture cycle means you stay dry and comfortable from warm-up to cool-down, avoiding the chill that comes from a damp baselayer. The fast-dry performance also makes this top practical for back-to-back training days, as it can be laundered and ready to wear again in minimal time.
Under Armour’s Anti-Odor Technology is built directly into the fabric to prevent the growth of odor-causing microbes at the source. Rather than simply masking unpleasant smells with fragrance, the technology inhibits the bacteria that produce them, keeping the garment genuinely fresh through extended use and multiple wash cycles. This makes the ColdGear® Compression Mock an ideal choice for training sessions, team sports, and outdoor activities where maintaining personal freshness is just as important as staying warm.
The raised mock collar provides meaningful additional coverage around the neck — one of the most vulnerable areas to wind and cold exposure during outdoor sport. Unlike a standard crew neck, the mock neck seals the gap between your baselayer and your outer layers, reducing heat loss significantly. Complementing this is an ergonomic seam construction that places flatlock seams away from high-abrasion zones at the shoulders and underarms, eliminating the friction hotspots that cause irritation during repetitive athletic movement. The dropped, shaped hem ensures the top stays in place and provides full core coverage throughout your activity.
