UPSURF Surfboard fins k2.1 5fins Single tab Surfing fins Honeycomb Choose Color (Red)

Haven't had them in the water yet but can say they appear to be a decent set of fins for the price. I matched them to the K2.1 FCS I have and the templates match. There appears to be carbon in the shaded areas and is definitely not paint.

The fins are made of good quality materials and work exactly the same as the real Kelly Slater 2.1 fins I've used for years!I highly recommend these fins.

A decent alternative fin to get you back into the qater. Should be used as spare. Not built for performance.

They fit good showed up on time easy to install.

Garbage. These don't even come close to fitting in a future box. Don't waste your money.

Poorly made product. I also wanted fins for a quad and didn’t receive that

Good fins
