The Whizz SLS, Duotone's newest addition to its foil range, specifically designed for dedicated prone and wake foiling. This lineup complements our Carve 2.0 and Glide series, crafted with the goal of creating a wing that pumps effortlessly for linking multiple waves and offers exceptional maneuverability for executing tight turns on the wave. The Whizz SLS features a mid-aspect ratio of 8.5, enough to balance efficient pumping capabilities with maneuverability. Its straight outline with zero sweep maximizes lift-to-drag ratio, enhancing pumping efficiency. The wing's unique appearance, especially from the front view, features a progressive dihedral shape that makes the Whizz feel exceptionally playful and responsive.

Duotone team utilized a robust airfoil design similar to Glide 2145 pump wing, delaying stall and allowing riders to kick out of waves at low speeds while continuing to pump effectively. Each size of the Whizz wings is fine-tuned with adjusted thickness and camber to ensure a broad speed range and powerful lift at slow speeds.
