In the world of ridiculous extra baggage fees, packing light is all but a necessity these days. Unless you happen to be spending time on a bike in which case you can say to hell with it and pack whatever will fit in your bag. If you’re talking about a Mission Workshop bag, like the new Fitzroy Rucksack, that means carrying pretty much everything but the kitchen sink if you so desire. The Fitzroy starts with the tried and true Mission Workshop DNA (multiple waterproof compartments, urethane coated zippers, the color black, etc.), but ditches the roll top in favor of an expandable compartment with clasp closures that will fit an entire day’s worth of deliveries for a business or 90% of your most valuable possessions.
