The women's Victory tank top by Under Armour is a mesh racer back tank with slim fit, Signature Moisture Transport System for moisture control, and lightweight stretch construction. Polyester/Elastane. In 1996, Kevin Plank, a 23-year-old former University of Maryland special teams captain, turned an idea born on the football field into a new industry that changed the way athletes dress forever. Plank named his new company Under Armour, and after extensive research on the athletic benefits of synthetic fabrics, he designed the first Under Armour HeatGear T-shirt. Engineered with moisture-wicking performance fibers, the shirt helps keep athletes cool, dry, and light in the most brutally hot conditions.
