MFC H1 Racing Fin
Get the fastest speed out of your fast board with a fast fin! The thin profile and custom flex pattern is possible with CNC shaped G10 on the Maui Fin Company H1. This gives you early planning and lots of speed. Designed to avoid cavitation at very high speeds, you will have the confidence to push your gear to new PRs on your GPS. The black pigmentation of the G10 is absorbed by the resin to help create a very smooth surface that helps increases speed.
