I have been using this device on my work belt for over a year. My jobs include everything from felling trees and driving tractors to clearing bushes and digging ponds. The material contains diesel, gasoline, petroleum, light battery acid sweat and more sweat. When I first got this leg holster, I sewed the holster in place. Adding to that the addition of an extra elastic band around the grip of my pistol, this sheath held up surprisingly well. This pocket holds my phone in a ziplock bag and the extra Molly is nice too. All buckles are still functional as well as the button buckle thumb release. This is a great value for money and worth more than anything I've spent so long buying.
