If you're watching Jordan Spieth play golf, you probably notice the Under Armour logo on the front of his hat.
Then, when you see him from behind, you notice another logo on the back of his hat that kind of looks like a couple of staples together. That's Jordan Spieth's personal logo, as created in conjunction with Under Armour. That JS logo is not only found on his hat -- which you can buy from UA and other retailers -- but you can also buy them on Spieth-branded shirts, also sold by Under Armour.
For the uninitiated or unaware, a number of golfers has personal logos. The trend really began with Tiger Woods, who developed a personal logo with Nike that went through one iteration before landing on the current TW logo that appears on all of his Nike clothes.
Adam Scott, Sergio Garcia, Hunter Mahan and Dustin Johnson are among those with personal logos that you'll see on Sundays.
