The Donut 90 SL is the ultralight version of AirDesign's proven Donut reserve for pilots whose all-up weight stays under 90 kg. At 810 g, it is significantly lighter than the standard Donut 100. It is EN 12491 certified in its own right: in certification testing it opened in about 3.1 s with a sink rate of about 5.5 m/s at its 90 kg maximum load. Built for pilots who prioritise minimum weight — hike & fly, speed-wing, and mountain pilots who want a trustworthy reserve without the extra grams.
