JUMBOgrabby began as an enlarged Grabsack, big enough to carry a 13-inch laptop. It didn’t go far beyond that. There’s a full-width inner sleeve pocket, so you can separate tech from glop; and there’s a zipper outer pocket thieves can’t get to because it’s against your hip. Perfect as a briefcase, purse, book bag, light shopper, and camera bag. Made with waterproofed Scottish cotton (we’re the only U.S. source of this ultra-fab that we know of) and the best military spec nylon, wooden toggles, shock cord, and brass O-rings available. The quality is immediately evident, and we’ve kept geekery to a minimum, emphasizing ease of use, quality fabrics, and the best workmanship.
