The SX4 is perfect for intermediate surfers who are looking to push their performance in 2-4ft surf. It has a medium entry rocker and a low exit rocker at the tail kick to enable the surfer to skip through flat sections with ease. This is the ultimate summer fun fish! It has tonnes of floatation, allowing you to surf it 2-3 inches shorter than your regular board. This board is a must for those looking to maximize performance in smaller surf.
