For those trips when a small backpack simply won't do, there's Topo's Mountain Duffel bag. This beefy 61.4-liter long-haul bag has enough room for all your extended trip gear in its spacious main compartment, but still has enough external and internal secondary pockets and pouches to allow for a good deal of organization. It's also built from sturdy 1000D Cordura ballistic nylon, has a coated pack cloth interior lining, features multiple carry handles as well as stowable backpack straps, and is equipped with water-resistant YKK zippers and heavy duty plastic hardware. Best of all, this USA-made duffel bag features a padded base and sides to keep all your gear safe in transit.
