Technical Features
4th Generation Construction
The SOUL⁴ builds on the continuous evolution of proven design principles. All components are engineered for durability, ease of use and reproducible performance — even under heavy everyday use.
Optimized Aerodynamics
Refinements in profile shaping and load distribution deliver even better upwind performance, stable power generation and consistent force delivery throughout the wind window.
Fine-Tuned Bridle
A precisely tuned bridle setup improves feedback and reduces bar pressure. The result is noticeably smoother handling combined with high stability. Durable bridle lines with high shape stability and low maintenance requirements.
Fast Inflation & Drainage
Improved airflow management and structural stability enable fast inflation and controlled flight behavior from the very start — especially in light wind conditions. An integrated drainage system expels water from the profile.
Performance Parameters
Jumping & Hangtime
Easy-to-time take-off with strong lift and long hangtime. No tendency to overfly and significantly easier landings. Compared to the SOUL3 it jumps better and turns tighter — jump more often, more precisely, and reach new heights with full control.
Power & Upwind
Accessible, smooth power delivery combined with an efficient glide ratio. Excellent upwind performance with reduced lateral forces — powerful without being overwhelming.
Handling & Feel
Intuitive and comfortable from the very first moment. Stable and precise positioning in the wind window, reduced backstall, clean turning behavior and easily controllable depower with lighter bar forces.
Reliability
Easy launching, reliable relaunching and fast inflation. An efficient session saver in 10–15 knots. Compared to the SONIC5 it sits deeper in the wind window and offers more accessible power and an easier relaunch.
Who is SOUL⁴ for
One Kite for Everything
The most versatile all-around kite in the Flysurfer range. Freeride, freestyle and foil — on water, snow and land. The one-kite solution for foil and twintip setups and a worry-free companion for travel. SOUL is all you need.
Transitioning from LEI to Foil Kites
Coming from an inflatable kite? The SOUL⁴ gives you reliable launch, relaunch, depower and upwind — all critical functions work intuitively from your very first session. From entry level to expert.
Hydrofoil & Light Wind
An excellent kite for hydrofoiling: precise feedback, early upwind ability, and the 18 m² gets going from just 7 knots. More height, more control, less stress — while everyone else is sitting on the beach, you ride.
