Whether it's because of a clumsy caddy or a tantrum over missing an easy putt, most golfers have had their clubs spill out of their bag once or twice. Kaala's Evolution Bag will ensure your gear stays inside no matter how much jostling is going on. The bag keeps your clubs sealed in, covered by a plastic shell. You rotate a top-mounted dial to the appropriate number or letter and a carousel delivers your stick of choice. Aside from protecting against club spillage, the Evolution is also safer in foul weather and easy to organize. The basic version is $430 and a self-propelled model (yes, it's motorized, so you can spend all your energy whacking balls into the water and not hauling your bag) costs $865.
