Get yourself a Titleist ball marker hat. Just don't lose the ball marker. The only way to replace it is to buy a new hat. Titleist doesn't have just the ball marker.

There are a lot of people who have a hat missing the ball marker, myself included. Do a search, this has been asked many many times.

Matt, the quickest way I can recommend to you is to pick up a hat with the official Titleist logo'd magnetic ball marker.  The hats come in 6 different colors, see below.  I am also attaching the link for ease.

Can always check out ebay as well.   I just bought a little gift pack with a nice Titleist tin, Sharpie marker with Titleist logo, 6 Titlesit tees, 3 ProV1 balls, and a decent ball marker with the Titleist logo on one side and ProV1 logo on the other.  Too bad I wont get to keep it thoguh being I bought it for a raflle for our get together.   But pretty cool little gift pack if your not wanting to buy a new hat just for the ball marker.   Something like this just without the FILA logo..

Or you can get to be great friends with your Club Pro (who supports Titleist) and evey once in a while he can pick up a little gem to give you as well..... BTW Curtis has a great idea.  Nice combo kit Curtis

I always use the pin that comes in the club cameron set.  Simply detach the needle part and they are great.  This years puzzle JYD is awesome!!
