[Radical4 SUPAIR Manual]

Light and compact, easy to install and use, listening to your movements to allow the pilot to play freely, to go fast, better, high and far.

The RADICAL, in its fourth generation, is a pioneer in walk and fly harnessing and still loves the mountains and vertical slopes.

The RADICAL4 is an ultra-light string harness (920g in size M) designed for mountain flying.

When used with the optional airbag, it becomes a harness with airbag protection, a rescue pocket and a reversible bag. This option makes it a versatile harness for safety on demand... and above all simplicity at every stage (the risers are delivered with the airbag)

Its sleek design expresses the spirit in which it was conceived: to keep only the essential to enhance the flying experience. Its featherweight does not detract from its comfort, thanks to its foamed back, nor from its efficiency in turns: the support is precise, cushioned (the independent leg straps, stiffened with mylar, pleasantly erase the irregularities of the air mass) and balanced (its structure cleans up the parasitic movements).
The RADICAL4 gives "a sensation of smooth control, of controlled gliding", describes Yoann Chavanne, its designer. This soft precision while riding is explained by its ability to deform to adapt to the rider's body.

Well accessorised (pole holder, removable waist belt) the RADICAL4 reveals itself in its finishing details. You can feel it with your eyes: every useful detail, every finish, every material chosen for its nobility and durability. The structure of the strap and the frame, the subcutaneous airbag repositioned in front of the harness and using a rush designed with a resistant material, have been thought to improve safety. The rucksack and harness have been designed separately to push the technical and aesthetic solutions to their limits.

Freedom, lightness, simplicity, because when there is nothing left to remove, the important thing remains.



Supair is a pioneering paragliding brand, born in Haute-Savoie in 1979 thanks to the innovative spirit of Pierre Bouilloux and mountain thermals. Its common thread: the pleasure of flying, closeness to paragliders, excellence and teamwork. And they have never lost the thread. SUPAIR harnesses are inscribed in the memory of free flight. Their canopies are instinctive with a reassuring feel. The accessories accompany you in the air. The SUPAIR brand brings together designers, children of flight, and stratospheric imaginations to design outdoor products. Literally. We don't put on airs, we simply look like what we are: an efficient, well-groomed brand that is open to the freedom of the winds. Since the beginnings of paragliding, the brand has remained faithful to the creative and adventurous spirit of the pioneers, to facilitate access to the air for all new paragliders and to imagine new, innovative products and services. Everything had to be invented in the first Supair flights. Everything is still to be invented with each flight in our community.
