The RADICAL 4
- A light and versatile mountain harness, designed with hike and fly in mind.
- It's suitable for a wide range of users, from leisure pilots to more experienced mountaineers. Building on the strengths of the RADICAL 3, the RADICAL 4 has been designed in order to offer a modern hike and fly harness with sleek lines. The comfort of the harness is optimized to be able to spend several hours soaring and thermaling.
- It also offers the possibility to connect the optional extra RADICAL 4 Airbag-Backpack Module, sold separately, converting the RADICAL 4 into a light reversible harness with airbag protection and an integrated under seat reserve compartment.
- Particularly adapted for your mountain, hike and ﬂy ﬂights, the Radical 4 is a light reversible harness with a removable airbag, including a rescue integrated under the harness.
- Light and compact, easy to install and use, it adapts to your movements to allow the pilot to play freely, to go fast, better, high and far.
The RADICAL 4 is the pioneer harness for hike and ﬂy. In its fourth generation it still loves the mountains and vertical slopes.
The Radical 4 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.
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.
Supair RADICAL 4 Airbag-Backpack
Designed only for the Supair RADICAL 4 mountain harness.
- Airbag-Backpack Module
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 an open face helmet.
Size M weighs 1270 grams.
