Supair Radical 4 BACK COUNTRY Harness Light And Flexible For Hike & Fly
The Supair Radical 4 Harness turns into a reversible backpack for walking up. It incorporates the possibility of connecting a removable airbag module with an integrated rescue parachute pocket under the seat for safety on demand… and mainly simplicity at every step.Supair Radical 4 harness
Walk lightly, put into action easily, fly with confidence. The Radical 4 takes you up into the mountains, with a take-off from an incomparable viewpoint, at the time of the ascents, after a phase of skiing, fast-hiking, or even climbing.Supair Radical 4 harness
Its refined design embodies the spirit in which it was conceived: to keep only the essential to magnify the experience in flight. Its light weight does not reduce its comfort, thanks to its foamed back, nor its efficiency in turns: the support is precise, damped (the independent leg straps, stiffened with mylar, erase the irregularities of the air mass), and balanced (its structure erase the parasitic movements).Supair Radical 4 harness
Particularly suitable for your mountain and hike & fly session, the Radical 4 is a lightweight reversible harness with a removable airbag module, including an integrated reserve parachute subcutaneous in the harness.tandem paraglider
Its pure design expresses the spirit in which it was conceived: to keep only the essential to magnify the experience in flight. Its light weight does not take anything away from its comfort, thanks to its foamed back, nor from its efficiency in the turns: the support is precise, damped (the independent legstraps , stiffened with mylar, gums up the irregularities of the air mass) and balanced (its structure cleans up the parasite movements).
The RADICAL4 gives “a feeling of smooth control, of controlled glide”, describes Yoann Chavanne, its designer. This soft precision in driving is explained by its capacity to deform itself to adapt to the pilot’s body.
Well accessorized (pole holder, removable waist belt) the RADICAL4 reveals itself in its finishing details. You can touch it with your eyes: every useful detail, every worked 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 backpack and the 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.
