Cool old shearling vest. Talon zipper looks like a 1930s or 1940s based on the Talon zipper identification guides publicly available. This type of thing was often worn as a base layer for pilots, military. Could also have been workwear, biker? The binding around the edges is very frayed. Has one hole above a pocket, lots of staining especially on the back. Or you could call that great patina.
