New snorkel kits from U.S. Divers come with fins that are 40 percent smaller than typical flippers, yet still give a powerful kick. Sold with a nylon bag that holds the mask, snorkel, and fins, they're easy to pack and cheaper than renting for a week--and with your own set, there are no worries about putting your face and feet where dozens of travelers have been before you (available at llbean.com, $59).
