Under Armour ColdGear® Fitted Mock 1366066 – Built for Cold, Made to Move
Stay Warm Without the Bulk
Cold weather can make your workouts uncomfortable and distracting. If you're tired of stiff layers that slow you down or ride up while you move, the Under Armour ColdGear® Fitted Mock 1366066 solves that problem. This baselayer is designed to keep you warm, dry, and focused—without the bulk or discomfort of traditional cold-weather gear.
Its dual-layer fabric features a soft, brushed interior for maximum warmth and a smooth, fast-drying exterior that keeps you dry during intense activity. Whether you're training outdoors, running in cold weather, or staying active in winter, this fitted mock gives you the coverage and comfort you need.
Performance You Can Count On
With a streamlined fit that sits between loose and compression, this top moves with your body. The 4-way stretch material ensures you can twist, bend, and reach in every direction without restriction. Stretch-mesh panels under the arms and along the back provide airflow where you need it most—offering ventilation without sacrificing warmth.
Its ergonomic design keeps seams away from high-abrasion areas, helping prevent irritation during long wear. The mock neck offers added coverage for wind protection, and the dropped, shaped hem ensures better coverage during movement. Choose from sharp colors like white, black, marine olive drab green, charcoal light heather, or midnight navy to match your style.
