Eagle Creek Packable Duffel 3005cu in

On some trips you know you'll be returning with more stuff than you had when you left. The Eagle Creek Packable Duffel packs into its own pocket, so you can stow it in your main pack until you need to haul all your goodies and souvenirs back home. This duffel doesn't come with loads of bullion, but its burly polyester ripstop could probably hold it. A generous 50 liters of space lets you stash all the cash you can handle, or just an extra change of gym clothes.
