Key Features
Dual-Layer Fabric Construction
One of the standout features of the Under Armour Men's ColdGear Compression Mock is its innovative dual-layer fabric. The interior boasts an ultra-warm, brushed finish that traps heat close to the skin, while the exterior is smooth and fast-drying, shedding moisture to keep you dry and comfortable.

Strategic Ventilation via Stretch-Mesh Panels
To strike the perfect balance between warmth and breathability, the shirt incorporates stretch-mesh panels on the back and underarms. These areas allow for crucial ventilation, helping to regulate your body temperature during intense activity without compromising the overall insulation.
