The Ono Twin Keel fins are machine foiled from a solid sheet of G10 fiberglass.
Designed for your more traditional fish.
 
We're releasing the Ono Keel fins in our Apex Series construction; made with a solid piece of precision foiled G10 fiberglass for the ultimate in performance and durability. The combination of highly durable material and precision foiling yield a fin that is stronger and has a more ideal flex pattern than your traditional honeycomb or composite fins.
 
G10 is made by compressing layers of fiberglass and epoxy resin and baking it an autoclave to have the maximum strength of any fiberglass available.
