Kalani Lattanzi is a waterman who rides big waves without a board. Watch him in action at some of the world's heaviest spots. He's just 23-years-old, but has taken an ancient sport – bodysurfing – and brought it to some of the biggest and heaviest waves on the planet, from Hawaii to his home in Brazil and the current darling of the big-wave world, Nazaré in Portugal. Yes, you're reading correctly, he bodysurfs big waves. Really, really big waves.
