Under Armour Men's Big & Tall UA Rival Fleece Pant

Founded in 1996 by Kevin Plank, a former University of Maryland football player, Under Armour® apparel is engineered to keep athletes cool, dry, and light throughout the course of a game, practice, or workout. Starting with a simple plan to make a superior T-shirt that provided compression, wicked perspiration off the skin, and worked with the body to regulate temperature, Under Armour has developed into a unique line of microfiber gear.

Under Armour's mission is to provide men, women, and youth with technically-advanced products engineered with a superior fabric construction, moisture management, and proven innovation. The company's products are sold worldwide and worn by professional football, baseball, and soccer players, as well as many collegiate and Olympic athletes.

The technology behind Under Armour's eclectic product assortment is complex, but reaping the benefits is simple: when it's hot, wear HeatGear®, when it's cold, wear ColdGear®, and when the climate is somewhere between those extremes, there's AllSeasonGear®.
