Fin Solution FCS Surfboard Fins

A clear quad is the workhorse nobody talks about: the set you put in and forget, fast off the bottom, holding through the turn, no drama.

This is the Fin Solution FCS-compatible set in clear, a fiberglass fin with a honeycomb core and a machine-foiled template for consistent flex. The G-series sweep sits around 33 degrees. It drops into FCS twin-tab boxes and works as a thruster, quad or side-bite setup depending on how you run it. Sizing is by rider weight.
