The Occy FCS fins are made in Glass Flex making them very stiff fins and thus very responsive. These fins also have a very moderate flex to them giving you just the right amount of speed without losing maneuverability.

The Occy fins have a very large fin area which is perfect for heavy surfers. This will allow you to apply tons of pressure on your backfoot without the tail of your surfboard sliding out.
