If you've tuned into the 2016 Ryder Cup, you may well have noticed that a good chunk of the European players aren't wearing hats. And that might seem jarring since not everyone has the beautiful mane Robert Rock does, and the Euros aren't paying tribute to the crestfallen Englishman.
It's unusual to see golfers not wearing hats, but for the Ryder Cup, none of the players are explicitly required to wear a hat while they're playing at Hazeltine National. Many of the Europeans, including Rory McIlroy, Lee Westwood and Sergio Garcia, are choosing to go hat-less. Meanwhile, Justin Rose and Henrik Stenson have decided to put on the caps while playing.
On the American side, the players are all wearing New Era-created hats which are scripted by day. On Friday, the Americans are going with gray. However, the players aren't all wearing the same style of hat. For instance, Patrick Reed is wearing a FlexFit-style hat while his playing partner Jordan Spieth is wearing a traditional closure ball cap.
