## Description

Ideal for beach breaks, the FCS II Reactor PC Large Tri Fin Set enables swift, tight turns and speedy maneuvers.

Review: Quick rail to rail - These fins are my favorite and remind me of old K fins (Kelly Slater 2.1) as they allow for quick rail to rail transitions. Great for punchy beach breaks. Has good release off the top to break your fins free, but enough hold to not lose control.
