NEW SEASON COLORS 24/25

Complimenting the ever popular AM template which sits in the Carver family and is more suited to longer drawn-out turns, the CI upright can be paired to a variety of CI models and is designed for speed & tight turns.

  • Overview

    The upright nature of this template promotes tighter turns and therefore comes to life in punchy, hollow waves and when performing vertical turns, but it will also suit conditions where you need immediate start-up speed from the take off. The full, robust profile of this fin from base-to-tip allows surfers to push hard while still getting that freedom to turn easily.

    "We designed the CI Upright because our surfboard range extended well into the hybrid and step-down categories and we needed a fin to maintain response and turning performance on our boards where the rocker was a little more relaxed and flatter".

    "This fin allows you to gain start-up drive and acceleration really quickly, yet still feel loose and free off the top. Many of our team riders have also gravitated to this fin on their high-performance shortboards and step-ups where they wanted less resistance and the ability to stay right in the pocket". - Britt Merrick

    • A collaboration with Channel Islands Surfboards, the CI Upright is designed for speed & tight turns.
    • A template that comes to life in punchy hollow waves, but can also suit conditions where you need the start up speed to get going.

    • Hollow steep waves, punchy beach breaks.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Performance boards with relaxed rocker.

  • Performance Core

    Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.

    Super fun!
    Size: 8.5, Color: Red Pepper
    These are so fantastic! The color is amazing! It is a bit on the tomato-red side of the color-wheel. The fit is great. They are comfortable from the 1st step. Easy to walk in.

    Footbed very soft and cushiony
    Size: 9, Color: Sand
    It was so comfortable even though it was a half size too small so i was able to exchange for a larger size. I originally ordered a size 9 and exchanged for a 9.5. I haven’t received the 9.5 yet but I am sure I am going to love them. They are so cute and go with everything.

    I wanted to love these....
    Size: 8, Color: Sand
    I really wanted to love these, and I *almost* did. They are comfortable and cute. But they are a little wide across the mid-foot so they were a little sloppy on my feet. The platform is quite high, and while at 5'3" I appreciated the extra height, between that and being too wide, I felt they were an accident waiting to happen. If they were slightly more narrow and a little lower, I would have been in love, but I had to return them. They seem true to size except for the extra width.
