The closest that is available only comes in white with black letters and does not have the pro titleist logo on the back nor the FJ logo on the side. They can be ordered thru your Titleist retail account. It is in the Spring 2022 catalog. Sometimes the items you see on the pros/caddies are not available to the public.

Found the bucket hats in white, black and navy. They a featured on the Titleist.com China and Korea sites. Do not think they ship to the US. Those colors could be previous season. You might call around to some stores and clubs, especially store that might have closeouts.

The caddie was rocking green and then red buckets. Too bad Titleist doesn’t offer more of what is seen on broadcasts to the general public
