The swallow tail version of the already super versatile Monsta Box allows you to surf it in an even wider range of conditions. Now available in Hyfi.

The Monsta Box is a medley of the Monsta and the Blak Box .. A one board quiver to suit a whole range of riders and conditions. Here's how they've merged the two global favourites to make it:-

  • It has less rocker than the Monsta , but more rocker than the Blak Box

  • It has a wider outline than the Monsta, but narrower than the Blak Box . The result is an outline that hides a surprising amount of area for ease of paddling and speed generation

  • The entry and exit rocker of both models has been blended to create a perfect balance and to maintain a responsive, high performance feel

  • Single to double concave

The result is a board with 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.

Wave Type: The Monsta Box is suitable for all wave types from 1-6ft.

Rocker: Medium to low rocker

Rails: Medium to full rails

Fin Set Up: Thruster

Hyfi Technology - After two years of research and development between top engineers and some of the world's best riders and over 100 prototype combinations of templates and materials, the resulting Hyfi (Hybrid Fiber) is an exclusive multi layer construction comprising of a stringerless EPS core with a mesh exoskeleton. Lighter, faster and stronger, the Hyfi creates the perfect flex properties for maximum performance. Carbon is added in all the right places for strength and rigidity and something called Olefin Fibres in other areas that require more flex as well as strength.

Picking up a Hyfi, you will definitely notice how much lighter these are than your usual PU board. (20% by all accounts). It should be noted that this doesn't mean you go way lower in volume, thinking it's going to be a lot more bouyant. The guys at JS say not to change your board length at all, and stick with what you normally ride.
Strength wise, Hyfi boards are reportedly 30% stronger than standard PU surfboards.
