This is a unique, very good-looking vintage backpack by Barbour with the British Union Jack design theme. It has a cinch top opening with rain cover flap. There are two front pockets with buckle closures and two webbing pockets as well.
It come with canvas adjustable shoulder straps and a stout leather carry handle.
Interior lining is all intact. There are no interior pockets.
The only "flaw" is it is missing the leather buckle/tang with quick-detach magnet for the main fold-over flap, but with some sleuthing a replacement probably can be found on-line. You can decern what is missing in the next to last photo.
Base to opening: 16"
Base width: 12"
Base depth: 6"
Light wear.
