Sounds like a Players Deep Back, which are currently available.

Thanks Gary for responding to my post. I cannot find the deep back cap you referenced in your post. The only cap that I have found that was deep back, black with red Titleist letters with white bordering the red Titleist letters had the adjustable strap on the back of the cap. I am trying to find the same cap without the strap. Again, thanks for taking the time to respond to my post.

Are you sure it was black? There is a navy blue dobby tech which looks like what you describe, except it's not black. The only other explanation is that it could be a previous years style. Along with golflocker.com, check out pgatoursuperstore.com
