Rory McIlroy and Jason Day will be among the 12 Nike athletes to wear the latest apparel and footwear for the first major of the season. Two key apparel technologies will help to keep the 13 Nike athletes who are competing in this year’s first major championship cool and comfortable throughout an entire round of golf: Aeroreact, a responsive lightweight fabric that is uniquely engineered to adapt to changes in an athlete’s temperature, and Zonal Cooling, which provides optimal breathability where the body produces the most heat.

As for shoes, Rory McIlroy will wear the Nike Lunar Control Vapor, including a new PE on Sunday. For his first major tournament as a Nike athlete, Jason Day will compete in Air Zoom TW 71 PEs during all four days of the tournament.

Here’s a head-to-toe look at what McIlroy and Day will wear on each day of the tournament:
