Cheap solar shower. It wasn't a high quality product - one time the shower head fell off the hose in the middle of a shower, and it was a bit awkward to fill and hang the bag in a suitable place. Also, maybe the water would have heated up enough to be worth it if left in the sun all day, but it wasn't often I would want to plan for that.
Heavy plastic and aluminum 250 cm double blade paddle with canoe grip handles that could be used to turn it into two canoe paddles. It was too heavy to be of any advantage in circumstances where one might use a double blade and when split into two canoe paddles they were a bit long (as well as heavy). The idea of multifunction gear appeals to me but as others have noted sometimes multi-function means not really useful for any function.
