These fins are limited edition, only available through MC Surfboards. MC's Fins are made by Naked Viking in San Diego/USA.
All Fins are made of G10 material, which is 60 layers of 2oz Fibreglass compressed in Epoxy resin and then foiled by a CNC machine. This gives them superior stiffness in the base and flex in the tip, which gives the fin incredible memory and speed through the water.
