I have 2 shirts that have a titleist tag inside they are polo/golf shirts they also have the world titleist on the chest and FJ on one sleeve what types of shirts are these. My uncle said he wanted them to wear and asked if he could have them but I caught him looking at eBay for prices of shirts when I asked him he said they wasn't worth much and he would give me a few bucks for them. Why do most shirts say FJ on the inside tag? Do I have a titleist shirt or a FJ shirt? Are they the same company? the Shirts were given to me by a golf instructor years ago
