Whether bodyboarding or bodysurfing, Viper V5 Fins are the perfect choice. A five inch blade with slanted/narrow tipped side rails gives you the powerful thrust you need, and Viper V5's are super lightweight and feel like an extension of your foot. The power of the Viper V5 Fin doesn't come from rigidity, but from the patented design that creates torque and "snap" that really blasts you through those waves.
