Product Description

Surfboard fin

Tail fins for beginners in surfing

Tril fins are the most common combination among surfers because triple fins increase stability, control and maneuverability. They can be used smoothly by beginners or professionals and are more suitable for modern high-performance shortboards.

These fins were far nicer than I expected. Literally the exact same as any "high quality" fin on the market. I gave them a good test for about 3 weeks, almost surfing every day from Linda Mar to Santa Cruz. Unfortunately, I was inju3 in a climbing accident recently and looks like the board will be hung up for the rest of the winter season. But they are awesome fins for sure. Took awhile to come in though... So keep that in mind if you're in a pinch.

After two surfs, my fiancé really likes these fins. He says he feels he goes faster and throws more spray. After using plastic ones all of his life, he is definitely sold on this material going forward and won't ever surf the lesser quality ones again. Material matters.

Center fin foil is off-center. Left fin tip is delaminated. When placed in fin boxes, left vs right fins are not symmetrically canted. Do not waste your money on these, unless your surfboard's main purpose is decor.

Great fins, look good too. Way better than the original fins the board came with. Fit into slots perfectly fine for me.

Zero complains.They flex a little like the more expensive versions and had zero issues with them popping into the slots.

The tip of the side fin is so sharp it tore a good chunk of my foot skin from a light contact moving from a sitting position on my board to prone. I compared them more closely to my other fins and they're definitely sharper.They also don't sit flush on the board.

No problems with shipping. Product appears as advertised and so far performed as expected. I would/will order more fins from Upsurf.
