RADICAL 4: light, simple, flexible. For hike & fly.
Thanks to its comfort, its lightness and its simplicity, the RADICAL 4 is suitable for both leisure pilots and more experienced mountaineers looking for a technical and accessorized product for the mountains. With its foam back and stiffened leg straps thanks to mylar, the comfort of the harness is optimized to be able to spend several hours in the air and fly in thermals or soaring.
Light and compact, easy to put on and use, the RADICAL 4 adapts to your movements to allow the pilot to play freely, to go fast, better, high and far. The RADICAL was the pioneer harness for hike and fly. In its fourth generation it still loves the mountains and vertical slopes.
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.
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, neither 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).
The RADICAL 4 gives “a feeling of smooth control, of controlled glide”, describes Yoann Chavanne, its designer. This soft precision in piloting is explained by its capacity to deform itself to adapt to the body of the pilot.
Well accessorized (pole holder, removable chest strap) the RADICAL 4 reveals itself in its finishing details. We touch with our 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 relocated in front of the harness and using a rush designed with a resistant material, have been thought to improve safety. The backpack 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.
The RADICAL 4 can be transformed into a light reversible harness-backpack with the optional extra Airbag-Backpack Module fitted. More info below.

RADICAL 4 Airbag-Backpack Module
The RADICAL 4 offers the possibility to connect a removable airbag / reversible backpack module, which includes airbag protection and a reserve parachute compartment integrated under the seat.
Pre-shaped, the airbag has been reworked compared to the RADICAL 3 version. It comes further forward of the harness and uses a new, stronger material. Certification tests have confirmed it offers optimum safety.
The module is also reversible into a roll-top backpack, accessorized for the mountain (multiple easily accessible pockets, a baton holder, ice axe holder, hydration system pocket…). Its new ergonomic straps and removable belt allow a high carry with a light backpack or a classic portage when the backpack is heavier. The backpack is adapted to the pilot’s morphology, with a larger backrest on size L than on sizes S and M. The volume of the carrying bag is larger than on the RADICAL 3. It has been designed to hold a LEAF 2 Light glider, a reserve parachute and a open face helmet.
