The Cotopaxi Allpa Getaway 70L Duffel is a big travel duffel for longer trips where you need serious capacity without serious weight. The backpack straps come out when you need them, and the whole bag stuffs into an included sack that doubles as a packing cube.
It is a lot of bag for very little weight, and the removable harness makes a big load easier to move.
Travelers heading out for a week or more who want a high-capacity hauler that can double as a backpack. Big enough to pack the whole crew's gear for a trip into the Collegiate Peaks.
