Steven Enns designed Transfold Backpack, which is made of a natural vegetable-tanned leather and features a really cool, origami-style expansion and contraction system. The folds in the leather create a three-dimensional pattern when not much is packed in the bag. Fill it up and the leather “stretches” out to accommodate more, making it the only bag you’ll ever need.

The leather will age over time the more it’s used, archiving your story of every day life, creating a bond between you and the bag.
