The K2 Alpha Keel Twin fin by Futures Fins is a smaller and more refined version of a large traditional keel fin template, which allows for more flex and manoeuvrability.
The K2 Alpha Keel fin is a smaller keel fin compared to the Futures K1 Keel, which also offers more flex due to the Alpha fin construction. You could think of the K2 Keel fins as a size medium and the K1 Keel fins as a size large.
The K2 Alpha Keel Twin which is made in California features a solid truss for extra support and incorporates Bureos NetPlus recycled fishing nets. This makes it a great environmentally conscious purchase if you're looking for a sustainable surfboard fin.
The Alpha construction combined with the K2 template allows you to manoeuvre your board more easily while maintaining the classic glide, control and trim that traditional keel fins offer.
