Are you green-minded? The outside of the Urban is made from recycled inner tubes, the zip-pull was once a valve and the strap started out in life as a seatbelt.
Those tubes have been seam-sealed to keep water out – rain can sneak in at the corners, but not much. The easy-access pocket on the ﬂap has a water-resistant zip too, making this a good all-weather option.
But bear in mind that although you can get a 17in laptop inside, there’s no padding to protect it (or you from it). You do, however, get some neat internal pockets, a chest strap that can run either way and broad reﬂective strips on the back. Volume is 16.5L.
