This is Kai’s go-to fin for modern-style logging. The Spiral’s medium base and tapered tip deliver a super-balanced blend of drive and speed while staying loose. This fin is designed for fast, sharp turns off the tail while delivering plenty of hold from the nose. Solid in all single fin wave conditions, this fin is perfect for modern logging with speed down the line and flow in connecting turns.

Kai’s HiPro center fin is built for powerful, driving, radical surfing when mounted in a HiPro longboard or mid-length and when matched up with a set of Kai’s HP side fins. Speed and power and flow are what these fins are all about.

These side fins are super-fast and full of drive. Their balanced foil generates lots of lift for accelerating speed in turns without creating excess drag when going down the line. They match up perfectly with Kai’s HP center fin as well as any proper HiPro center fin in the market. Go with smaller sides when paired with longer centers and smaller conditions/surfers. Run with bigger sides when going with smaller center fins or looking for more drive off the rail in larger waves/surfers.
