This hunting jacket was made by Ralph Lauren as part of their now defunct Polo Sportsman line. It is made of brown canvas and is sort of a greatest hits version of 1910s-1930s hunting jackets, drawing mainly from the detailing of Red Head and Duxbak designs. It has a front entry half-moon style game pouch, double breast pocket and double round cargo pockets. The shoulders are reinforced and there is corduroy on the collar and inside the cuffs. The sleeves have double ventilated armpit gussets, the collar has a buttoned throat latch, and the cuffs have a distinctive button closure, which, unlike the rest of the detailing of the coat, I do not recognize.
Chest (pit to pit): 25″ (doubled = 50″)
