The Firewire Twinzer Fin by Stu Kenson is a four-fin configuration that delivers the smooth, controlled drive of a twin with the added stability of a second set of smaller fins — one of the most unique and rewarding fin setups available for mid-lengths and fishes.

Key Features:

• Twinzer Configuration — dual pairs of fins (two main fins + two canard fins) for a distinctive smooth, flowing feel through turns
• Stu Kenson Design — crafted by the fin maker who pioneered the Twinzer concept
• High-Flex Template — delivers a lively, responsive feel with natural spring through turns
• Futures Single Tab Compatible — fits Futures fin boxes (single tab versions)
• Arm Colorway — distinctive finish that identifies the Twinzer line in the Firewire range
• Works on Fish, Mid-Length, and Twin Shapes — ideal pairing for Firewire fish and alternative shapes

The Twinzer generates speed and flow that a traditional twin can't replicate. If you've never surfed a Twinzer setup, this is the fin to start with — Kenson's design makes it accessible and immediately enjoyable across a wide range of boards and wave types.

Compatibility: Fits Futures fin boxes (single tab). Check your board's fin box configuration before ordering.

Care: Rinse with fresh water after saltwater use. Store fins out of direct UV exposure when not in use.
