here are some spec they give on the website for the leather and kydex
Better Quality Components - We looked at the materials used by Crossbreed, Galco, and Desantis and we chose our material to be several grades higher in every regard. Really.
-- Leather - We use premium 10-12 ounce drum dyed leather that is 100% SWEATPROOF and WATERPROOF and will remain so for life. Others use 8 ounce leather and they try to combat the sweat issue by selling you horsehide. For example, Crossbreed offers horsehide for a *surcharge*, but HORSEHIDE IS NOT SWEATPROOF. Theirs is not drum dyed, and it is not a comfy 10-12 ounce leather.
-- Plastic - Our plastic outer shells are built better by using .093 thick material that covers the gun much better and has a more attractive finish. Our shells are molded to the bottom edge of the gun to protect the front sights from impact and to prevent the pistol from wearing a hole in your garments. Crossbreed, Galco, and virtually everyone else only use a small amount of a very thin .060 plastic and leave most of the firearm exposed. Sure, it's easier to manufacture that way, but it's not the best way to make a holster
