The award-winning design team at Notabag presents a duffle that transforms into a backpack and back again, whenever you feel like it. It's made from rugged cotton and ripstop nylon with tough webbing straps you can pull through the buckles on one side of the bag to activate backpack mode. There's a separate ventilated compartment to stow a pair of shoes too, and it's all sealed up behind the water-resistant shell.
