PGA Championship 2017: Jordan Spieth will rely on Under Armour's most innovative pieces of apparel

Jordan Spieth has become more comfortable wearing louder, bolder colors, and his PGA Championship looks will showcase his new affinity in a fun, fresh way. You'll see him wear a bright jade green throughout the championship, grounding this strong color with navys, whites and grays.

More notable than the colors he'll wear, however, is the technology he'll rely on to stay cool during Charlotte's hot and humid August climate. The polos Spieth will rely on are finished with a coating that's designed to pull heat away from the body, helping an athlete perform longer under extreme heat. The CoolSwitch Brassie Stripe polo ($75) he'll showcase on Sunday is Under Armour's latest offering, which is not only designed with the company's heat-wicking technology, but also a unique pattern of engineered stripes.

Spieth will pair these polos with his trusty Match Play straight-leg trousers ($60) and the Spieth One shoes ($170), which he helped design.

Under Armour has made it easy to shop each of Spieth's outfits: You can buy his Thursday outfit here, Friday here, Saturday here and Sunday here.
