Getting ready to sail to the Mexican Rivera? The Bahamas? Grand Cayman? You'll look as gorgeous as the turquoise waters off the coast. If you're on a cruise and happen to fall overboard, just flip the Caribbean Sea visor over and signal SOS with the bright white underside to the captain. He'll spin that ship around and in no time, you'll be enjoying that Pina Colada back on the Lido Deck!
