This jacket was made recently by Eddie Bauer, drawing influence from 1930s work jackets (the overall cut, belt back, throat latch, unlined construction) and from Air Force Nomex flight jackets (the pocket design, style of zipper). It makes for a very rugged, outdoorsy lightweight jacket with a great vintage feel to it.
This jacket was sold by Eddie Bauer. It is made from Indian Blanket style wool fabric- from the texture and particular pattern, I would guess made by the Woolrich Woolen Mills. The jacket has a leather collar and corozo buttons. It is fully lined. Despite being labeled a size Medium, with a 54″ chest, this would best fit someone who wears a size 48 jacket.
