Geared toward minimalist travelers or day-trippers (“one-way ticket, yeah”) this offering from Norway-based Douchebags boasts a 15-liter volume with an integrated laptop sleeve; a side opening allowing for easy access to your goods; a waterproof construction (minus the zippers); and ABS protective “ribs” that will safeguard your valuables. It can be attached via a hook-up system to any other Douchebags product—wheeled or non-wheeled. The Douchebag, above, and also the Big Bastard roller bag, are prime examples. After all, consolidation is key when it comes to efficient travel.
