About this fin
We’re proud to collaborate with Alex Lopez on his go-to template, the Diamond Twin - a versatile hybrid twin designed for speed and control. With a 5.35" base and 5.25" depth, it delivers strong drive off the bottom while its refined, raked tip adds sensitivity for quick, precise direction changes. From round pins and long fish to performance twinnies, the Diamond Twin brings acceleration, flow, and confident hold to a wide range of boards.
