Is it a tote? Is it a duffel? It's both, and the NEMO Double Haul Convertible Duffel 30L Bag absolutely rules. Whether we're packing for a quick overnight or bringing home a week's worth of groceries from the farmer's market, the dual-use design has us covered. It quickly transitions from duffel mode to tote mode, utilizing an internal frame that keeps the bag open while in tote mode and conveniently packing down small when we're getting ready for travel. The 30-liter capacity is perfectly sized for daily use as a gym bag and offers plenty of space for weekend getaways, keeping whatever cargo we're packing protected with the heavy-duty, urethane-coated material. A large zippered pocket on the exterior of the bag allows us to stash smaller items like our wallet or sunglasses, and the padded backpack straps make it easy to quickly tour a city by foot when we have a long layover.
