We have everything from base layers to beanie hats. Our Under Armour collection also features HeatGear and ColdGear material technologies to help regulate your temperature, no matter what sport or activity you’re working up a sweat for.

Under Armour – The Beginning

Under Armour is an American supplier of sportswear and casual clothing – which launched on a very small scale in 1996, so the brand is relatively new compared to some of the other sports clothing brands we stock. Its founder, an American football fullback, was growing tired of his shirts under his jersey becoming sweaty during play. He noticed that his compression shorts were staying dry, which gave him the idea of offering specially made compression shirts to prevent sweating on the top half of the body. He started the business in his grandmother’s basement in Washington, D.C, selling his clothing range from the boot of his car.

Under Armour - Today

Under Armour was propelled into the spotlight when Warner Brothers featured the brand in two of its films, leading to the founder placing an ad in the ESPN magazine – which generated almost 1 million dollars in sales. Today, Under Armour has grown into an internationally recognised sport apparel company and offers top quality compression clothing and other performance apparel to its customers worldwide.
