These Pacific Vibrations Tomo Quad fins are built for speed and super sharp turns. They've got a futuristic look and are designed to sit deep in the water, which creates lift and helps you accelerate down the line. The cut-away base combined with the flat foil on both the front and rear fins lets you change direction really quickly and makes the board feel super maneuverable. They're built with a honeycomb core and fiberglass construction, finished with a cool blue resin. The fronts are 4.71\ tall with a 3.59\ base, and the rears are 4.24\ tall with the same 3.59\ base. They fit standard Futures fin boxes. If you're looking to add some serious drive and responsiveness to your shortboard or fish, these quads are a rad choice.
