Selling my Mission Workshop Rummy (27L) Messenger Bag. I've had it for about 3 years now but haven't used it much the past year and a half. I stopped using it because I upgraded bags a little over a year ago. It still has tons of life left. In my opinion its the best messenger bag out there. It's waterproof. It can be closed in the tradition "flap down" configuration or roll top as well. The shoulder strap can be adjusted to be worn over your right shoulder or your left shoulder. Also comes with a cross-chest stabilizer for when you want to secure the back in place. Awesome bag, if you have any questions let me know.
