In recent years golf's four Major championships have had an increasingly popular sideshow. What golfers wear on the course is big business and retailers want to make sure they're stocking what you see on your favourite pro so you can add the look to your wardrobe.
Players will have picked gear to benefit performance - especially at Valhalla where keeping cool on the course could be an important step to a Wannamaker trophy - and many, as you know, have their own particular favourite colours to identify them on Sunday.
We've put together the best of the "scripting" to help you spot your men over the four days.
The hottest player in the field followed his Open victory in July by taking last weeks WGC Bridgestone Invitational and he's sticking to the winning formula as he looks to pick up his second US PGA title, wearing the same Nike Innovation Colour Polo as at Hoylake.

The heat is on Rickie in more ways than one this week as he's one of our betting tips but at least his Cobra Puma gear will help him better the heat and humidity of Kentucky. No surprise that he's in orange on Sunday and if you like the cut of his jib why not enter our caption competition to be dressed head to toe in this Puma AW14 gear.
Blixt's had a tough season following his outstanding tie for second place at the US Masters but the Swede fits in well with Cobra Puma's modern styling and he'll have some Swedish Blue in his outfit if he is in contention on Sunday afternoon.
