Lightweight Safety For Pilots Who Need More Capacity
The AirDesign DONUT SL 110 delivers exceptional passive safety for pilots flying higher all-up weights without the bulk traditionally associated with larger reserve parachutes. Weighing only 1.04kg including its deployment container, it combines advanced load distribution, a highly refined hybrid canopy design and exceptional packing practicality into one of the lightest reserves in its class.
A Lightweight Reserve That Doesn’t Compromise On Capacity
Finding a lightweight reserve parachute is relatively easy.
Finding a lightweight reserve parachute capable of supporting higher all-up flying weights without compromising safety, durability or ease of use is considerably harder.
That challenge formed the foundation of the DONUT SL 110.
Designed specifically for pilots operating at higher certified take-off weights, the DONUT SL 110 remains true to AirDesign’s Superlight philosophy while incorporating significant engineering enhancements to ensure exceptional strength, stability and reliability.
The result is a reserve parachute that provides the confidence of a larger safety system without forcing pilots to carry unnecessary weight.
DONUT vs DONUT SL – What’s the Difference?
The DONUT SL 110 is based on the same proven safety architecture as the standard DONUT 110.
Both reserves share AirDesign’s distinctive hybrid design philosophy, combining the stability benefits of a square reserve with the deployment simplicity of a round reserve.
The DONUT SL version has been specifically developed for pilots seeking to minimise weight and pack volume while retaining certified safety performance.
Through the use of carefully selected lightweight materials, advanced load management and refined construction techniques, the DONUT SL 110 achieves a remarkably low weight of only 1.04kg including its deployment container.
Unlike many ultra-light reserves that prioritise weight above all else, AirDesign intentionally selected materials that maintain long-term durability and structural integrity while still delivering meaningful weight savings.
Choose the Standard DONUT If:
- Weight and volume are not major considerations
- Maximum durability is your primary goal
- You fly a larger harness with generous reserve space
- You simply want a robust everyday reserve solution
Choose the DONUT SL 110 If:
- You want the lightest reserve possible for your weight category
- You fly a lightweight harness
- You travel frequently with your equipment
- You want to reduce overall equipment weight
- You value compact packing volume and portability
Advanced Engineering For Higher Loads
The DONUT SL 110 is more than simply a larger version of the SL 90.
To accommodate higher maximum take-off weights, AirDesign developed a unique architecture that optimises load distribution across the entire canopy.
Working closely with Edelrid’s R&D department, AirDesign refined the internal structure to improve force dissipation and ensure loads are distributed efficiently throughout the reserve.
The square-inspired canopy geometry further enhances stability while helping manage loading more effectively during deployment and descent.
The result is exceptional strength and passive safety without a corresponding increase in weight.
Designed To Deploy Quickly
The deployment pod has been specifically engineered to maximise extraction reliability.
Features include:
- Two-stage deployment sequence
- Suspension lines released before canopy inflation
- Low-friction extraction flap
- Faster and smoother deployment from the harness container
- Improved deployment consistency
Every design decision has been made with one objective in mind: helping the reserve deploy quickly and reliably when required.
Designed To Pack Easily
AirDesign understands that a reserve parachute that is difficult to repack is less likely to receive the regular maintenance it deserves.
To simplify the process, the DONUT SL 110 incorporates several pilot-focused features:
- Integrated folding loops for easier canopy organisation
- Colour-coded line architecture
- Precisely dimensioned line lengths
- Oversized deployment pod for easier packing
- Improved canopy management during repacks
These seemingly small details help reduce packing complexity while improving confidence that the reserve is correctly prepared.

Cloudbase Recommendation
The DONUT SL 110 is ideal for pilots who require a higher certified reserve capacity but refuse to accept the weight penalty traditionally associated with larger emergency parachutes.
For cross-country pilots, travelling pilots, lightweight harness users and anyone seeking maximum passive safety at higher all-up weights, the DONUT SL 110 represents one of the most refined and capable lightweight reserve systems currently available.
