Selling an almost new AirDesign Donut 100 Rescue
The DONUT rescue system combines the advantages of cross and round caps. The DONUT is cut like a cross cap, but looks more like a round cap. This keeps packing as simple as usual - just like a round cap.
Its suitability for everyday use has been put through its paces in many drop tests. The DONUT retains its properties (such as pendulum stability and sink rate) even after repeated throwing and after water landings.
The advantages summarized:
High pendulum stability
Low sink rates
Pickup in Ampass (near Stubaital, Austria) or EU shipping possible.
