The all-new 4.0 fastlight thruster fin features the 3DFINS patented Dimpled Technology and the fastlight glass layup makes for a lighter, smoother flex pattern, This creates a super high-performance, the perfect size for a grom or someone looking for a smaller "fun" fin.
Refining the flex pattern gives back some of the power load into the fins, giving it a super snappy, more lively feeling on smaller waves. Created using a hex-core construction finished with fiberglass makes for a strong and durable thruster.
