Fast, drivey and able to push hard, the FCS M7 Cleanline GF Tri Fins are reliable pricepoint carvers. The M-Series has a flexible tip for forgiveness and control at high speed. The Inside Foil Technology offers superior drive and hold. Glass Flex construction offers the flex pattern of a hand-foiled fiberglass fin combined with the ability to mold highly technical computer generated foils accurately, meaning your fins are precision dialed. Tagged with our Cleanline rock logo and ready for action, these limited edition M7 Fins are begging to get wet.


Injection molding process ensures geometric accuracy and provides a reliable and consistent feel. These fins are ideal for novice surfers because the relaxed (subtle) flex of these fins can be engaged with minimal effort, and as the flex returns to a neutral position the fin produces a whip-like effect that propels the board forward, and helps to maintain speed and acceleration.

FCS Fins M7 Cleanline Glass Flex Tri Fin Set Great service and timely Delivery Review by Nando Nando
The fins arrived quickly and in perfect condition. You also included a ‘free’ bar of wax! Thank you! I would recommend purchasing from your site. If I require anything surf related I’ll order again from Surfline.
