Oilskin

What is oilskin? Oilskin is a waxed or oiled cotton fabric known for its wind-resistant and water-repellent properties, as well as excellent breathability. The term "oilskin" is also used metaphorically for leather or other greased materials.
Originally invented by British sailors in the 18th century, oilskin was made by soaking old sails in provisioning oils to better protect themselves from the elements. Even today, cotton fabrics are immersed in oil or wax before production, with excess liquid pressed out using heavy rollers.
There are various types of oilskin, mainly differing in fabric choice and coating appearance. Ancient oilskin typically involves a lightweight cotton fabric coated with antique wax, resulting in a shiny surface where water beads off in droplets. Dry oilskin, on the other hand, is usually made of heavy canvas fabric with a barely visible or palpable coating. Despite the different coating methods, the impregnation of the fabrics lasts for years if proper cleaning and care are observed. It is advisable to clean textiles made of oilskin by hand under cold water rather than using a washing machine.
This material is primarily used for weather-resistant clothing that can withstand outdoor activities, such as hats and caps.
