US Box Fin MX Evo 21cm Select SM027050021
Description: The MX Evo is a compact, high-performance US box fin engineered for explosive acceleration and precise control in freestyle and performance surfing. Constructed with a super-stiff blade profile from base to tip, the fin drives quickly out of turns and helps the board plane earlier for faster top-end speed. Its compact outline and positive rake provide excellent bite and hold through carves while remaining agile for quick direction changes. Built for durability, the MX Evo uses a high-stiffness composite construction designed to withstand repetitive loading without flexing excessively. The result is confident propulsion, improved response on rail-to-rail maneuvers, and reduced drag compared with more flexible fins. This unisex, adult-sized 21 cm fin fits standard US box setups and pairs well with neoprene booties or traction pads as part of a complete performance setup.
