4.5" Surf Fin Set (4 Fins)

A set of four flexible 4.5-inch surf fins, built for moving water. They flex before they break, so when a fin contacts a rock or the bottom, the material bends and springs back instead of snapping the fin or damaging your board. These are river fins. The give that protects them on rocky, shallow lines is the same give that keeps a hard impact from cracking a fin box. Buy the set of four as a backup, a replacement, or a full swap. Fits the Axis model Hydrus river boards and the Hydrus iSUP board.
