The JS Black Box 3 HYFI Swallow Tail Surfboard is every day all around a surfboard. One of the most versatile surfboard models in the world, this is the board that gives you the greatest chance for maximum fun and peak performance in all conditions. It’s by far JS's most popular surfboard globally. It creates speed instantly when the waves are small thanks to its fuller outline and low entry/exit rockers, yet still has the ability to handle when the swell’s up due to its subtle bottom contours and performance hip squash tail. All of these design features combine to create an incredibly balanced every day all arounder. For the widest range of people and the widest range of waves, the Blak Box 3 is your new best friend!

The Blak Box 3 performs best in waves that are fat and crumbly but goes equally well when it's clean and hollow. Best wave height is between 0 and 4 feet. The Blak Box 3 is fast, maneuverable and super rippable! It's perfect in average conditions when most high-performance boards are struggling.

Hybrid Fiber Diamond
The technology behind JS's Hybrid Fiber Diamond construction was pulled from a variety of high impact, long-lasting boardsport manufacturing techniques. The development team started with the most flexible base they could imagine, an EPS core with no stringer, and from there began the painstaking process of balancing strength, weight, and flex. The goal with HyFi was to create an ultra-high performance board that would go the distance, even at professional level contest weight.

Rigorously tested with the JS team, it took an exact combination of materials, layering processes, and exclusive construction techniques to create the incredibly durable exoskeleton we now know as HyFi. The result is more spring, more speed, and more acceleration. Precision engineered to be faster, stronger and lighter than anything else out there Hybrid Fiber Diamond is pushing the limits of modern surfboard technology. HyFi, welcome to the future.
