Eagle Creek says:
Our smallest Cargo Hauler Duffel 40L is ultra-light and durable, for even the most handy baggage-handlers who give it the ol’ heave-ho. Extra gear pockets make convenient places to put those items you don’t want to lose, like your winnings from a weekend in Vegas. No matter where you go or what you do, the Cargo Hauler will get you there. It’s convenient, resilient, and makes a great carry-on.
