Under Armour

Under Armour was formed in 1996 by University of Maryland football player Kevin Plank, who was frustrated by his sweat soaked under jersey. Noting that his compression shorts were able to remain dry, Plank worked alongside fellow student, Jordan Lindgren to develop a compression base layer that let moisture escape, whilst allowing the body to retain heat. Word of mouth carried their business out of Plank's grandmother's basement and across many local sports teams, who found an immediate use for their innovations.

The brand’s big break came when USA Today pictured an Oakland Raiders player wearing their mock turtleneck top on its front page. From there the business has gone from strength to strength. Sportsmen and women from all mediums continue to wear the base layer clothing as well as military units, who use Under Armour when serving in hot climates. The company’s golf ambassadors include the 2015 Masters and U.S. Open winner Jordan Spieth, Hunter Mahan, Matthew Fitzpatrick and Alison Lee.

In 2016 Under Armour unveiled its long-awaited range of golf shoes to the world, with rave reviews with the help of former World Number 1, Jordan Spieth. Since this time, the golf shoe range has expanded to a variety of styles fit for the modern day golfer. The latest Charged Phantom SL Golf Shoes, take the comfort of your favourite trainer and add all the performance and traction of a traditional golf shoe to give players the best of both worlds.
