The Monsta Box is the perfect combination of two stellar designs. It takes the rocker and outlines of the Monsta 6 and the Blak Box 2 and splits the difference, resulting in a board that has ample volume but keeps it hidden. This allows it to thrive in average conditions, but also be surfed in solid, high-performance waves. It is fast and maneuverable, and the addition of a squash tail gives the board more release off the snap, resulting in a top-notch high-performance groveler that doesn’t bog when the waves turn on.

The Monsta Box comes with a stock thruster setup, and is the go-to board for Australian phenom Mikey Wright (the hard-charging brother of Owen and Tyler). Other team riders with this board in their quivers include Adrian Buchan, Dusty Payne, Joel Parkinson, and Owen Wright. Whether competing in a jersey or going for a free surf, the Monsta Box with a squash tail is a reliable tool for these tour stalwarts, and is just as forgiving and rippable for the average surfer as well. If you are looking for a single board that can cover most of your bases, this is a great option to check out and try.



Jason Stevenson and his JS label (famous for the tractor logo) have been producing some of the most high-performance surfboards on the planet for more than two decades. No one questions the design elements of these boards, and a number of guys on the world tour ride them, including Julian Wilson, Owen Wright, Adrian “Ace” Buchan and Joel Parkinson. But what many people don’t realize is that the technology that goes into the construction of the boards is just as cutting edge as their design.

JS offers their range of boards in the HYFI construction, which is a hybrid fiber technology. The product of two years of research and development, HYFI is the latest and greatest in surfboard construction advances, producing light, strong, fast surfboards that are more durable than polyurethane boards, but ride just as well. The flex out of the tail adds more drive and projection, the boards are 20% lighter than PU boards (making them faster and more maneuverable), and they simply don’t ding as easily as normal glassed PU boards. The result is the ultimate strength-to-weight ratio, applied to some of the best designs in the surfboard industry. In other words, the perfect board.

JS offers a number of popular models in the HYFI construction, including the Monsta 6, the Air 17, the Monsta Box, the Blak Box II, the Ghetto Cat, the Psycho Nitro and the Flying Pony. Here at Hawaiian South Shore, we are excited to carry a number of JS’s HYFI boards. Come check them out—I’ve already added one to my personal quiver!
