A So Cal classic returns Sunday, pitting the best surfers against H2O boarders of the snowy type.

The awesome event combines a day of surfing at Huntington Beach Pier, dude, with a day on the mountain. This slopestyle competition will determine the overall Pro, Amateur and Industry board riders.

The event has seeds for 12 invited pro surfers and 12 invited pro snowboarders.  Two dozen amateurs and 12 industry shakers will also battle it out in their own divisions.

Past athletes have included Terje Haakonsen, Dave Downing, Jamie Lynn, CJ Hobgood, Christian Fletcher, Shane Beschen, Keith Malloy, and Gabe Taylor, along with 3-time overall champion, Troy Eckert.

Just try to remember to use the right board for the right H2O!
