I have some from a few year's ago in black with red trim and yes, they are heavy leather. Sorry to hear that you might have received some copies that are vinyl. We can't send you pictures of ours as the website no longer supports posting photos in thread replies.

Hi Dale
Thanks for the reply. Could you possibly weigh the ones you have?
That would give a good indication of fake or not.

Thanks for the reply, Dale. If you get a chance, could you weigh your covers?
Thanks
Steve

I don't really have anything to weigh them with. Sorry. My bathroom scales do pretty good at telling my to lay off the Thanksgiving leftovers but are not accurate enough for small items. I will say they are heavier than the TSi standard covers and even heavier than some other leather ones I have from Sunfish. The Titleist ones are thick leather and have a distinct pebble grain finish, not slick like many synthetic covers. Sorry I can't help you more. You might go into a golf retail store and see if they have some on the shelf. Mine were not fully wrapped so you can feel them unless Titleist changed the packaging since I got mine.

My premium leather TS driver cover is 145 g.

Thanks Don. I had one of those little portable scales but Capt. Danny Brown convocated it during a traffic stop in Richland County NC. #opnation

Steve,
there's a number of online retailers selling premium headcovers on eBay, if you've bought it from one of those they should be genuine, and if you have your doubts and haven't used them you should be ale to return them?
