How many gigantic walls have we seen it fall down at Jaws, Nazaré or Mavericks? At the age of 26, Kai Lenny is constantly pushing the boundaries of fat surfing. This year, the Hawaiian took advantage of the XXL swell like no one else. Tubes, carves, air, big waves have become his playground. Remember, the free surfer had already shared with us a completely crazy video about his best waves of the winter.

In his new edict, Kai changes his angle. With his Go Pro, he takes us to the heart of the most monstrous tubes on the planet. So when you see the surfer being swallowed under tons of water, you think you're pretty good on your side of the camera.
