Overview
Board Types
Performance Glass
Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
Small - Medium

Great fins - worked really well on my Seaside:)
Extremely stoked on the new retro keels, first time installing the FCS II fin system as a backyard board builder. Boxes came out nice and flush with perfect placement on a hand shaped 5’5” fish, retro keels not only look nice but performed nice on a head high to foot overhead swell here in Jersey the past few days, thanks for making such a great product!
Put these in a stretched out LSD 8’0 twin fin. Previously the board was fast but a little horizontal if that makes sense. These fins loosened it up but it still retained the drive. I am a massive fan 👌
feels good with nice drive out of turns
Noticed the lack of drag straight away whilst paddling! Turned my Bourton Hydro Twin into a straight line dragster! Love the retro template too.
