Oilskin
Le Roy used worn-out sailcloth painted with a mixture of linseed oil and wax to produce a waterproof garment suitable to be worn on deck in foul-weather conditions.Some early sou'westers and rain capes were handmade of sailcloth waterproofed with a thin layer of tar, while other methods involved[1] canvas duck coated with multiple applications of linseed oil and paint.Modern oilskins may be made of flexible PVC-coated synthetic fabric,[1] while advanced materials for extreme conditions such as yacht racing may be used.[citation needed] Also known as "foul weather gear", contemporary oilskins include such innovations as DWR-coated nylon on their low end[2] and Gore-Tex and other proprietary waterproof membranes on the high.[3] A Sou'wester, a traditional form of collapsible oilskin rain-hat, is longer in the back than the front to fully protect the neck.
