The two gloves I have also came from Alaskan Bowhunting Supply. I understand they are no longer available. The second glove is still brand new. the elastic wristband failed after several years on the first glove and I replaced it. The glove's cordovan finger tips are better than new.
I have in the meantime switched to a Bateman tab, left-handed, with Cordovan and a soft leather backing. I had to trim it down to the bare minimum length to avoid getting my lip slapped, but once I reached the proper length it is my favorite. I still use the glove when shooting right handed. For me, Cordovan is the only way to go. Slick, lasts forever, and I get as clean or cleaner release than with any other material I've ever tried.
