You are looking at a very special piece of Americana workwear history: a vintage 80s Filson single mackinaw charcoal buffalo plaid wool jacket, made in the USA. It's made from robust, densely woven, thick 26-ounce mackinaw wool sourced from Pendleton mills, unlike nowadays, when Filson mackinaw jackets are made from thinner 24 oz imported Mexican wool fabric. There is no scuffing, shedding, or any of the moth damages presented; it is in perfect condition.

Actual measurements laid flat:

pit to pit: 63cm
back length from collar seam to hem: 80cm
sleeve length from shoulder seam to cuff: 66cm
shoulder width: 50cm

Don't hesitate to ask me additional information.
