Oilskin

Oilskin is a waterproof fabric traditionally used by sailors, fishermen, and others working outdoors in wet conditions. It's created by treating cloth, most commonly cotton canvas, with oil, historically linseed oil, to render it impermeable to water. Modern oilskin may utilize alternative oils or synthetic coatings such as polyurethane or waxes to achieve similar waterproofing.

The process of creating oilskin involves saturating the fabric with the oil or coating and allowing it to cure or dry, creating a flexible yet water-resistant barrier. Multiple layers may be applied to enhance its protective qualities.

Oilskin garments, such as jackets, trousers, and hats, are prized for their durability and ability to withstand harsh weather. While initially stiff, oilskin becomes more pliable with use and develops a distinctive patina. Its breathability is limited compared to modern waterproof fabrics, but its robust nature and longevity have made it a long-standing choice for maritime and outdoor activities.

Care for oilskin typically involves cleaning with cold water and avoiding harsh detergents or solvents that can strip the protective coating. Re-oiling or waxing may be necessary periodically to maintain its waterproof qualities.
