Futures CI Upright Tri/Quad XL Fins (Item #118357)

Built for speed, control, and a more vertical attack, the Futures CI Upright Tri/Quad XL Fins are a high-performance fin set designed for surfers who like to surf tight in the pocket. With an upright template and responsive feel, these fins are ideal for generating quick direction changes while still holding strong through powerful turns.

Small shop note: Buying from Rider Shack supports a small, family-owned, core surf shop operated by surfers who are passionate about sharing the love of surfing and the ocean.

Performance Overview
