Layering is the key to keeping the cold at bay, and layers starts at the base level. The Under Armour Tactical Crew Base Long Sleeve Shirt (Tan 499) is Under Armour's solution to the base level that features a comfortable fit that isn't strangling and uses Under Armour's history of fabric technology to offer superior and intelligent insulation.

The fitted Under Armour tan 499 long sleeved shirt doesn't bunch while under clothes thanks to its fitted, next-to-skin cut without the squeeze of tighter clothing. UA's ColdGear Reactor is intelligent insulation that adapts to your activity level for the right breathability & warmth for the mission at hand. Inside the shirt are soft, brushed "nodes" for additional warmth and breathability and, like all UA gear, the material is built to wick sweat and dry quickly.
