Recently we heard about two kiteboard manufacturers using basalt fiber in their board construction.

The Naish Monarch 132×41 Kiteboard includes two layers of basalt fiber fabric. The result is a board that is strong and lightweight with lively response and flex characteristics.

Quote “Basalt is a natural volcanic fiber which offers vibration resistance and durability without compromising on reflex while still maintaining a high strength to weight ratio. It is naturally produced absent of toxic additives. The combination of wood core, with basalt laminate provides a flex characteristic which is unique to Cabrinha.” CBL Wakestyle / Cable
