An origami kayak?! The Oru Kayak is a clever, new kayak for those looking for an extremely portable kayak that takes up just a small amount of space. It can be assembled quickly and is recommended for use on flat water and mild waves. Made out of a single sheet of double-layered corrugated plastic, it is very durable, buoyant and stable. It’s a full-size kayak (12′ long by 25′ wide by 13” high) that only weighs 25 pounds. Wow!
