Levis Sherpa Trucker Type 3 four pocket style.  I bought this from a vintage shop maybe 15 years ago.  The labels and USA manufacture suggest it could date from the 1980s but that is just my guess.  22 inch pit to pit.  Some fading from dark indigo but the fabric still retains some stiffness.  Fleece is white.  I am selling another Sherpa slightly smaller so please see other listing.  Posting to U.K. Only.  Thanks for looking.
