I like the .080" in general but some colors I can only find in .093". IMO any of the thicknesses work fine for the Izula. I even think .060" is adequate. I have a Glock kydex IWB holster made from the .060" from FIST and it works great. Kydex is strong stuff.? for you folks making kydex sheaths. what weight material do you find works best? thanks. peace
