The Osprey Shuttle Wheeled Duffel, 32
Checked it in at the airport, and roll it smoothly off the baggage conveyer belt when you arrive. Unless you’re packing barbells, the Shuttle Wheeled Duffel, weighing in at less than 9 lbs, will maximize your usable space while keeping you safely below the 50 lb. threshold for extra baggage fees. (If you buy one of the monster-sized rolling duffel made by several companies, prepare to spend $50+ every time you check in to a flight, since you’ll almost always be over the weight limit. And their size virtually guarantees that you won’t get the wink-and-forget-about-it treatment from a friendly check in agent.)
From there, the bag is a great size to navigate narrow streets on rugged wheels, without the backbreaking strain of a traditional duffel. With Osprey’s traditional “burrito” design, the bag cinches down to remove unnecessary bulk, and doesn’t have all kinds of extraneous straps and loops that typically snag on conveyer belts, bus roof racks, and narrow aisles. The tough cordura padded exterior prevents cuts and scrapes from doing any meaningful damage and provides protection for everything packed inside. A zippered side pocket along with internal pockets and dividers ensure you won’t spend 15 minutes digging for that headlamp stuck in between your socks, and the over-sized wheels mean you won’t get knocked sideways by the cobblestones of Quito or the muddy streets of Sayulita.
