The square, hard-shelled design looks a bit clunky, but the functionality of this hybrid golf bag, available at retail later this year, is hard to argue with. Less than a foot wide and deep, the bag fits on a golf cart or can be attached to a push cart with little fuss. It's waterproof and has plenty of room for clubs, balls, accessories and apparel. When you're done with the round, put on the top and it doubles as a travel bag that can be checked as luggage at an airport. The $595 retail price is roughly what you'd pay separately for a quality cart bag and a travel bag. -- R.H.
