The origins of the the Driza-Bone can be traced to last century when a young Scottish migrant, Edward Le Roy, began making wet weather coats for windjammer sailors out of torn cotton sails waterproofed with linseed oil. These sailing ships travelled between Britain, Europe and Australia. Due to their iron hulls the ships travelled low in the water which meant that the sailors spent most of their time wet and required some form of wet weather gear to protect them.
Some of these sailors settled in Australia and Le Roy's coats became very popular with rural workers. In partnership with soap manufacturer T E Pearson, he began manufacturing the coats from a backyard shed in Manly. As the coat became more popular with rural workers its styling grandually changed to meet their needs. It was made longer for horse riding, and a fantail was placed in the centre back so it could comfortably fit over the horse and keep the saddle dry. Wrist straps stopped the arms getting cold and wet, and leg straps stopped the coat from flapping. A new oiling process was developed so that the coat wouldn't go hard and crack in the harsh dry conditions of the Australian bush. These refinements resulted in a range of practical hardwearing garments which have become increasingly identified as part of an Australian national costume.
