DESC: The best, lightest, most maneuverable Caboose yet! The Caboose Ultralight is so compact, maneuverable and lightweight you might forget that it's a tandem stroller. At a mere 21 pounds the Caboose Ultralight is 20% lighter weight than the original model and far lighter than most double strollers. The Ultralight is also ultra-maneuverable because it has sealed ball bearing wheels. (If that doesn't mean anything to you; it is faster and smoother. Think rollerblades and skateboards) Mom's and Dad's will really love the neoprene Cool Essentials Parent Organizer too. It has plenty of room to store your keys, cell phone, etc and the cup holder will help keep your drinks cool. The deluxe sun canopy will offer more protection for your children on sunny days out.
