At home in small to medium conditions, the JS Monsta Box HyFi Surfboard puts its emphasis on setting up for high flying airs and projecting to insane speeds quickly. After years of development and extensive series of tests, the JS team is confident that their Hybrid Fiber Diamond Construction is 30% stronger and 20% lighter than standard PU construction. Precision engineered to be faster, stronger and lighter than anything else out there, HyFi boards utilize cutting edge materials yet retain the ability for you to ride your normal dimensions in the improved technology.

The JS Monsta Box Surfboard combines the best of two boards into one user friendly performance machine. With a rocker and outline between that of the Monsta 6 and the Blak Box 2, the Monsta Box has perfectly blended curves to hide volume in all the right places, while remaining incredibly quick and reactive. A smooth single to double concave creates lift in sub-par conditions, but allows you to remain in control when the waves turn on. Coming standard with a 3-fin setup, the Monsta Box is a great performance oriented board that won't let you down, even in incredibly average surf.

CONSTRUCTION HyFi Construction

HyFi Construction

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.
