This vintage jacket was made in the 1940s under the WeatherBak label. This style was designed for hunters and fisherman, with space for every possible need. The canvas is advertised as “snag-pruf”, and the picture on the label of a hunter in the rain, along with the brand name reinforces the idea of water resistance which goes along whit this kind of tight, high quality canvas. Although canvas will get wet in the rain, the fibers swell with moisture, making a tight fabric even tighter, not allowing the water to actually pass through. I took some canvas gear on a canoe trip in Nova Scotia a year and a half ago. It rained the entire trip and my vintage canvas duffle was soaked, but everything inside remained dry.

The jacket has a short cut. There are pleated breast pockets, and wraparound double hip pockets. One has a divider with separate flaps, one has a single flap. There is a fly rod loop, a waist drawstring, pockets on each sleeve, and a roomy rear game pocket. There are two interior pockets. Room to fit everything you own! The underarms have open bottoms, an alternative to gussets for greater range of motion.

Chest (pit to pit): 23″
