I took this duffel on a 3 week trip to the Yucatan Peninsula. Long days wearing it on my back, rainstorms, bus rides, taxis, all the good stuff. It held up great in the rain and baggage handling. The extra compartment for dirty clothes was a plus, and didn't limit space when empty. There is a sweet pocket with a double-zipper for passports and wallets. I am also a big fan of the olive colorway.
Cost efficient, great layout of pockets, sweet double-zipper passport pocket, nice colorways, 40L is perfect size to check or carry-on
Cons: Backpack straps are too long (cut them off if you want), hand strap is in the way and uncomfortable when wearing as a backpack.
Overall, this is a great first attempt at a duffel for Backcountry. With a few adjustments, they will have a Black Hole killer.
