Proteck FCS Power Flex Safety Tri Fin Set-Black-4.0" DOORBUSTERWK1 Stops bar from moving upFrom Protect Power Flex is a Pro Teck Fin with a medium core flex. The smoke colored edge fin bends on turns, and then springs back, creating forward thrust similar to a swim fin. The medium flex core and flexible trailing edge makes the board turn smooth and fluid, with continuous speed. Power Flex Fins are recommended for intermediate to professional surfers.
