Supair Radical 4

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.

Technical Info

Supair RADICAL 4 Airbag-Backpack

Designed only for the Supair RADICAL 4 mountain harness.

Package

• Airbag-Backpack Module

Airbag

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.

Backpack

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.

Weight

Size M weighs 1270 grams.
