The FCS CI Upright PC Medium White Right Side Fin is a precision-engineered single fin designed in collaboration with Channel Islands Surfboards. The upright template produces lively pivot and quick direction changes, making it ideal for smaller, mushier surf where responsiveness is everything. Sold as a single right-side fin for replacing or customising your setup.

• Note: Right side fin only — sold as a single replacement fin

Sizing Note: FCS Medium fins are designed for surfers approximately 65–80kg (143–176lb). The CI Upright template suits surfers who like a snappy, pivoty feel, particularly in smaller or weaker conditions.

Care: Rinse with fresh water after each use. Store out of direct sunlight when possible. Check the fin base and plug tabs periodically for wear.
