    Super durable longboard fin!
  

*by S***N on Reviewed in the United States on May 7, 2020*

This longboard fun is so durable and flexible. The pin is adjustable and if the fin gets bent it’s easy to straighten out. Love the blue color too!  Glad it’s made in the USA!

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Flexible.
  

*by B***3 on Reviewed in the United States on July 15, 2020*

Fin worked well. Just wasn't as flexible as was required to paddle down rivers with rocks.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent quality product
  

*by L***H on Reviewed in the United States on November 29, 2018*

Gorgeous fin. Love the screw-in feature as it is super easy to lose your fins. The only downfall is I had to alter how the fin fits on my SUP.
