I posted this up on another thread about oilskin fabrics but I think this deserves to be here as well. Oilskin fabrics: Coats, Tents, Tarps, Scabbards. For water proof and wind resistant plus protective layer against the elements like thorns and cactus. Very durable and with multiple uses as a tool. Good for just about any environment and weather. The most widely recognized coat is the Australian Duster cowboy coat. These videos will show other objects from oilskin material and how to care for them.
This video he is using the Duster coat. I over looked these at first because I am not a cowboy, but practicality is what it is in which case is defined by necessity.
