I have a few of these bags left. If you're interested in buying one, throw me an email: firstname.lastname@example.org. They're 60 bucks + shipping, if you're outside of Columbia.
This is a super simple and sturdy musette bag made of 18oz cotton and 1000d Cordura nylon.
It features one inside pocket (with integrated pen pocket) and one outside pocket, plus key loop. Super limited edition.
15x11", 12x3" bottom.
