Located in Cape Hatteras. No bots.Designed by Britt Merrick, the CI Upright Quad Rears are shaped to pair seamlessly with the upright CI side fins. Featuring a neutral-raked template, they deliver a solid balance of control and stability while still allowing for tight, pivot-style turns.
A collaboration with Channel Islands Surfboards, the CI Upright is designed for speed and tight turns. This template comes to life in punchy, hollow waves, but also suits conditions where you need start-up speed to get going.

The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer maintain drive and hold through a turn. This versatile fin material is light and can be used in a variety of different conditions.
