Overview
Developed by Matt Biolos, the MB Quad Rears are designed to pair with his upright side fins, creating a loose and lively quad setup. Perfect for beach breaks and everyday waves, this set delivers a fast, responsive feel while still maintaining stability and flow through carves. The 80/20 foil encourages smooth, easy turning with added control, making it a versatile option for surfers looking to get the most out of their quad.
