The Le Grand Derriere (LGD) is a vintage reissue of a TOM BIHN design from the early 1990’. It’s, make no mistake, a large pack. Inside the main compartment, there’s an open-top pocket along the back panel that’ll fit an 11" iPad Pro, iPad mini, Kindle, or similarly-sized smaller tablet — or a notebook or paperback, if you’re working to minimize screen time. The rest of the main compartment is spacious and ready to fit a jacket, water bottle, and bento box. There’s four — yes, four — O-rings in the main compartment: two against the back panel and two against the front panel. That main compartment zipper is protected from the elements by a flap; some folks love flapped zippers as-is, and others find that adding the included Cord Zipper Pulls to the metal zipper pulls will make the main compartment easier to open and close.
