Under Armour makes performance apparel and footwear for athletes and professionals who need clothing that manages sweat and moves with them. Founded in 1996 by Kevin Plank, a former University of Maryland football player who started the company in his grandmother's basement, the brand built its name on a moisture-wicking compression shirt and grew into a full apparel and footwear line. Its gear is worn by athletes, military and law enforcement personnel, and active civilians.

Here you'll find Under Armour's tactical apparel and footwear — base layers, shirts, and outerwear alongside tactical boots built for duty wear — much of it based on the brand's HeatGear and ColdGear systems for hot and cold conditions. The UA Tactical line adapts these to uniform-appropriate colors and cuts.

The idea that started the company still defines the products: synthetic performance fabric that wicks moisture away from the skin and dries fast, keeping the wearer cooler and lighter than cotton during hard effort. HeatGear handles heat, ColdGear traps warmth in cold weather, and stretch construction preserves mobility for climbing, running, and hard movement. Under Armour's tactical boots carry the brand's athletic-footwear cushioning and support into patrol and field use, where long hours on foot make comfort, traction, and support matter as much as durability. Because clothing and boots that stay comfortable get worn on the longest days, that performance is what keeps the brand in rotation.

Build a layering system with performance shirts and jackets, add tactical boots and footwear, and round out a kit from the tactical apparel selection.
