Deflow Supra Quattro Quad Fins, Four-Fin Set

The Deflow Supra Quattro is the quad version of Deflow's Supra fin, a four-fin set for drive and speed on open-face waves. It combines Deflow's Arcco template with a medium flex pattern, with plenty of base for acceleration off bottom turns and a thinner tip for release.

Choosing quad fins

Check your board's fin box system before buying. This set comes with a single-tab base or an FCS1 twin tab base, so choose the option that matches the boxes in your board. Fin size is usually chosen by body weight, so check Deflow's size guide when choosing between M and L.

A quad setup gives speed down the line and hold on the face, and a medium flex fin adds some spring through turns. Rinse fins in fresh water after use and store them out of direct sunlight.
