This is another of Côte&Ciel’s premium accessories. The Flat backpack is made of waxed and coated “techno-canvas” with cotton lining, supports up to a 15″ Macbook Pro (or comparable laptop), a Pentax K-30 with 135mm lens and lens hood — a pretty big DSLR, along with your tablet of choice, a few cables, and a lip balm or similarly sized items, like SD cards or wallets. I’ve had The Flat backpack with me for a few days now and had the chance to take it out in a heavy New York City storm. It was comfortable, repelled water easily, got plenty of looks (or maybe it’s because I’m handsome?) and because the design is more of an “open-wide” enclosure rather than the traditional “zipper splits the whole thing”, it makes the backpack more streamlined, pretty much to its namesake — thus keeping it flat.
