Mid Fin Co. Matt Black - Common Single Fin A refined take on our common template, developed with Matt Vasquez for powerful, controlled longboard surfing. Built in a heavy k-fiber fiberglass construction , this fin offers a slightly more dependable feel while maintaining the smooth flex characteristics that make a traditional single fin feel alive underfoot. The result is a fin that delivers drive, stability, and clean rail-to-rail transitions without feeling overly rigid. Matt has spent extensive time pairing this fin with his 9’6 Brent Clem longboard , dialing in a balance that complements boards designed to be surfed with intention and control. The template provides strong hold through longer carving turns, confident trim at speed, and reliable projection when you step back on the tail. Finished in black , the Matt Black Signature keeps things simple and classic—built for surfers who appreciate a traditional feel with dependable performance.
