Folding Bag by Leeuw & Vormgeving

Usually the best designs don’t come from a design firm, but from Mother Nature. Inspired by the naturally armored armadillo, Leeuw & Vormgeving designed the Folding Bag. Sort of nature meets industrial design, it’s made from an aluminum polypropylene composite and takes design cues from the armadillo, making it a lightweight yet tough backpack design. Source
