Whaler's Wear is a type of clothing that was traditionally worn by sailors and whalers. It is made from a waterproof material called OILSKIN, which is a heavy cotton fabric that has been treated with linseed oil to make it impermeable to water. The fabric is usually dyed in dark colors such as navy blue or black, and the garments are designed to be durable and long-lasting. Whaler's Wear is still popular today among sailors and other outdoor enthusiasts who need protection from the elements.
