Waterproof Backpack for Urban Hipsters

I have a waterproof backpack for adventures in the dink, but it’s really just a dry-bag with straps. It’s bright yellow and made out of rubberized fabric, so it is neither subtle nor particularly comfortable for spending a day tramping around. To take my laptop or go shopping in an urban environment, I’d want something stylish and comfortable like the Chromebags Ivan. It’s got external pockets and messenger bag street cred, plus a roll-top dry bag integrated as the main compartment. Dude!
