This vintage hunting vest was made in the 1950s. It was sold by Sears under the Active sportswear label. Due to similarity in design and construction to their product, I would guess that this was made under contract by the Empire Mfg. Co. It has two large cargo pockets on the front with shotgun shell loops inside. There is a game pouch on the back.

Chest (pit to pit): 21-1/2″ (doubled =43″)
Length: 24-3/4″
