Question

Why do many of the pga golfers have red circles on their hats?

Answer 1

It's just the players who are under contract with Nike.  It's for the Nike One golf ball.  The Power of Red.

Answer 2

Those players who have the red circle on their hats are sponsored by Nike. It is part of the new Nike ONE logo. If you look closely, it actually says ONE on the hat, with the red circle around the "N". The letters ONE are stiched in the hat with the same colour thread as the rest of the hat.

Answer 3

Because it's their players badge. A lot of them wear their players ID ,so to speak, on their hats. some also wear them on their belts if you notice. (Unless of course you only noticed the players who are under Nike contract, who then have them for the Nike one golfball)

Answer 4

Tiger wears it to promote nike golf balls

Answer 5

The red circle is "part" of the Nike One galf ball logo.
