The F4 is the next generation in performance longboarding. This board is light, thin and fast, with a Quad fin option for those looking to loosen things up and take speed to the next level.
The F4 is super fast, and drives hard off the bottom with its pintail template and hard edges in the tail. The 17" nose will even let you sneak in a quick noseride.
This is one for the performance guy looking for great off-the-tail performance, and down-the-line speed. It's an essential to any serious longboarders quiver.
"Last weekend on my second ride, the true value of Quad fins, thinner pin tail and lightweight became apparent. This thing is fast..."

- SLX
- SLX EPOXY TECHNOLOGY
These boards are CNC milled from the shapers files and glassed by hand.
Laying up the glass this way allows us superior control of the strength to weight ratio of the boards.
SLX shapes provide the surfer with:
Controlled Flex - Each SLX board has it's a stringer and layup designed around the flex the shaper requires from each design. And it's all done by hand.
Lighter weight - You will immediately feel the light weight when picking this board up but the real benefit is the drive and projection off the bottom.You can find out more about GSI's surfboard construction on our surfboard technologies page

Graham Shephard from EAST SUSSE, United Kingdom says:
This is the most cantankerous, technical, unforgiving and badly behaved board it has been my pleasure to own in 38 years of surfing. But get it right and it flies off the bottom, snap back or round house it will do it all but come off your back foot and and it is is all change. I love it and once you remember that it has to be surfed and not just poked around it will always put a smile on your face. Yes it will nose ride but it will also nose dive much to the constant amusement and amazement of my French surfing friends. Cruiser, easy rider beginner/ intermediate board? Definitely not. Performance long board/ Oh yes.. (and all those fins to fiddle with!!!)
Greg from NSW, Australia says:
I bought thisspontaneously after snapping my Southpoint Bonga 9.1 mal in the surf the same morning near Bondi. after 2 funloving years Last weekend on my second ride, the true value of Quad fins, thinner pin tail and lightweight became apparent. This thing is fast compared to my old Schaper/Bonga but requires more paddling to get going. I love it!
