Engineered for the highest speed and efficiency possible, the HA850 is the smallest of our core wing-foiling and prone surf sizes. With less surface area and a higher stall speed, the HA850 is designed to generate maximum efficiency with minimum drag, also making it an ideal choice for high-speed wing foiling and kite foiling. The wingtip is designed for zero ventilation when you tip-breach, allowing you to crank faster, tighter radius turns. Needing minimal pump and power to generate glide, the HA850 is a stand-out wing for intermediate to advanced wing-foil riders.
