Engineered for Efficiency, Designed for Joy

Over the years, AirDesign has redefined what lightweight wings can achieve. Therefore, the SuSi 4 was built with purpose—not only to reduce weight, but also to maintain control, comfort, and confidence at every flight stage. While earlier versions delivered on this promise, the SuSi 4 takes things even further.

Why Pilots Choose the AirDesign SuSi 4

Lightweight Without Compromise

Designed for pilots who prioritize portability, the SuSi 4 weighs significantly less than traditional gliders. Even so, it doesn’t sacrifice durability or flight performance. Because of its compact build, whether you’re hiking remote peaks or boarding a plane, you’ll appreciate how effortlessly it fits into your adventure kit. Moreover, its lighter construction also translates to faster climbs and less fatigue on long treks.AirDesign SuSi 4

Intuitive Handling Meets Playful Precision

Once airborne, the SuSi 4 responds quickly and predictably. Brake pressure remains light, yet deliberate. Consequently, small inputs result in smooth, purposeful turns. Furthermore, the overall behavior remains forgiving, which means pilots can enjoy a playful flying style without compromising safety. Whether thermalling in weak lift or navigating narrow landings, you’ll always feel connected and in control.

AirDesign SuSi 4 Quick Launch, Confident Recovery

No matter the wind conditions, the wing inflates easily—even when conditions are flat calm. Additionally, its forgiving design corrects minor pilot input errors. Because of this, it’s suitable for a wide range of skill levels. It’s fast to rise, easy to center, and reliable from launch to landing. In contrast to heavier gliders, the SuSi 4 makes even low-wind launches feel manageable.

Built for All Kinds of Sky Lovers

For Hike-and-Fly Adventurers

Not every glider fits every journey. Thankfully, the AirDesign SuSi 4 was designed for hike-and-fly pilots who value lightness, reliability, and responsiveness. From the moment you pack it into your rucksack, you’ll notice its featherweight construction. Once you reach the summit, its smooth inflation and efficient launch ensure every climb is rewarded. Moreover, its minimalist pack volume allows for efficient storage, even in small hike packs.

For Backcountry and Vol-Biv Explorers

When you’re days away from roads or infrastructure, gear quality becomes essential. Because the SuSi 4 is compact and ultralight, it conserves energy on the ground and in flight. Additionally, its consistent handling allows for better decision-making in remote, unpredictable conditions. As a result, you’ll fly farther and safer during extended wilderness trips.

For Minimalist XC Enthusiasts

Even though the SuSi 4 is compact, it offers surprising glide efficiency. Thanks to its refined aspect ratio and aerodynamic profile, it climbs well and glides better. Consequently, short cross-country flights feel more capable and accessible—even in marginal conditions. In addition, transitioning between thermals feels smooth and stable, boosting pilot confidence during longer flights.

How the SuSi 4 Elevates Your Flight

Effortless Setup, Seamless Takeoff

Color-coded risers and a reduced line plan simplify every preflight inspection. As a result, you spend less time untangling lines and more time preparing mentally. Once you’re ready to launch, the SuSi 4 inflates predictably without surging or overshooting. Even on tight alpine launches, it offers confidence and composure. More importantly, its pitch stability and ease of inflation help reduce stress during technical takeoffs.

Stable Yet Dynamic Handling

The SuSi 4 masterfully balances safety with playful handling. Accordingly, you’ll enjoy a stable wing that doesn’t overreact in turbulent air. At the same time, it provides clear brake feedback. That means you’re always aware of what the glider is doing—whether you’re soaring or descending. Moreover, its direct response lets pilots refine their skills progressively, without frustration.

Control That Encourages Growth

Many ultralight wings can feel too sensitive or vague. Thankfully, the SuSi 4 is different. It delivers precise brake response while remaining forgiving to input. This blend promotes better technique, improves pilot awareness, and supports skill development—especially during thermalling and approach. Furthermore, its progressive behavior inspires confidence, encouraging pilots to push their comfort zone safely.

In addition, Dyneema lines provide strength with reduced drag, ensuring both longevity and performance. Moreover, this construction strategy aligns with the needs of long-term adventurers who prioritize reliability.AirDesign SuSi 4

Customizable Risers for Every Preference

Depending on your mission, you can choose standard risers, ultralight Dyneema risers, or the innovative Superlight option. Each version is thoughtfully designed to reduce bulk and maximize usability—so you can tailor your glider setup without compromise. For example, the Dyneema option works well for ultralight hike-and-fly, while standard risers offer traditional ease of handling.AirDesign SuSi 4
