I own several "WessonHide" belts and holsters. Mostly N frame holsters and 44 belt loop belts. Sorry, no pictures as my computer is on its last legs.

My reason for my original purchase of these units (new mid-80s), in addition to the low price point, was the fact that they were impervious to water and dirt. If you got them wet, or dirty, you just wiped down you pistol and wiped the holster and you were good to go. They also didn't stretch out and lose their shape. Not the prettiest holsters but functional. In the field style holsters there was/is not much difference in design just a different material.

Turner slings uses a product, now, to make rifle slings, called, I think, Biothane. I am sure it is a different chemical compound but the principle is the same. Less stretch and longer life while resistant to water and chemicals.
