Avid white-water kayakers fill their garages with boats of every shape and size, and rely on a ritual of paddle-tossing, Zen meditation, and luck to pick the perfect boat for any given river. The Transformer makes this ritual a whole lot simpler. Designed by World Freestyle Kayaking Champion Eric “E.J.” Jackson, the Transformer is the first kayak to offer three sets of interchangeable rubber tips, which customize the boat for river features and performance preferences, as well as providing shock absorption for the occasional scuffle with river rocks. $1,000-$1,200.
