The Hypto Krypto Fibre Flex model uses these to full effect, the premium quality EPS cores and carbon fibre rail surrounds of this new breed of surfboard are both lightweight and strong whilst maintaining maximum maneuverability and spring through turns. The carbon fibre rails protect against dings whilst providing the perfect amount of flex, the board will react more quickly to rider input and create more speed and drive through turns and critical sections. This Fibreflex technology produces a stronger, lighter more responsive surfboard which will benifit any surfer, in any conditions regardless of ability.
