Who says canoes can’t stow? The Adhoc Folding Canoe is the creation of designer Ori Levin, which turns an otherwise non-pliable vessel, into a foldable sloop that stashes into a standard sized backpack. Weighing just 9 lbs, the boat is made of a carbon fiber hull wrapped in aramid, a lightweight heat-resistant fabric normally used in racing sails. Bag to water? 5 minutes.
