Truly revolutionary SUP board here. Mainly for river rapid riding/ surfing. Fully wrapped in patented 3D fiberglass. This is apparently a “normal” board: hard-top, clear epoxy, same light core as our other boards, but thanks to our patented 3D glass and the application techniques, this board is extremely difficult, if not impossible to ding. That’s right, you can try, but a baseball bat blow, full force...bounces right off. A 12 lb sledge hammer, bounces right off. Now that we’ve painted an idea of the durability, we can talk about why. Mainly, river surfing; Rocks, stumps, and helmets (think about it) do nothing to this board. Finally, rapid surfers can lose the non-performing inflatables, cheap foamies, plastic toy boards, and the ding repair guys phone number. On top of all that, the board is a proven maneuverable surf shape, that tears it up in the type of currents and surf you'll hit in rapids. After all, your board should tear up the rapids, not the other way around.
