Lib Tech RRIP'S Fins


High performance up-cycled fins designed for optimal performance with Lib FOCII fin boxes. 

These fins have over 5/8” adjustability fore and aft in the Freedom of Choice Fin Box to fine tune your surfboard’s personality.

Lib Tech RRIPS fins are designed to fit LIB FOCII boxes only!

Since Every surfboard in the world is basically an oval shape cut out of rectangular fabrics, we’re saving the unused corners of our surfboard fabrics and we're makingfins out of them. Lib RRIP’s fin sets feature a lightweight Hexzylon Fiberfoam core, a reinforced carbon fiber biaxial base, and tensioned carbon fiber torsion rods on the tips for lively rebound response.

“Help save the planet one fin set at a time with our handcrafted American surfboard rubbish morphed into fine foiled fast fins.” ~ Mike Olson
