AIRBAG REACTOR
Discover OUR Reactor 2.0 SYSTEM, the lightest airbag on the market.

- Double airbag: Equipped with two 75L balloons, safety is doubled in the event of an accident.
- A unique design: The shape of our airbag protects your head, and its attachment system optimizes the upward force in an avalanche, thus promoting a return to the surface.
- The most powerful inflation system: A powerful airbag inflation capacity even under pressure, backed by two patents.
Weighing just 650g, the Reactor 2.0 is the lightest on the market. Its compact design allows it to take up less than 2 liters in the bag. This lightness and compactness offer optimal comfort for hikers and skiers without compromising safety performance, allowing for greater freedom of movement in the most demanding environments.



One of the main assets of our Reactor system is its versatility. Our airbag system is fully transferable to all our other bags.
The benefits:
- Change practices easily and quickly
- Upgrade your bag at low cost
- Act in favor of the planet by reusing your Reactor system. Only change the textile part, which has the lowest carbon emissions.
WHY THIS CHOICE?

With a carbon cartridge, the Arva Reactor is 10 to 30% lighter than battery-powered electrical systems, offering better balance and increased comfort without compromising your safety.

The Reactor’s Venturi system offers efficient inflation with an initial pressure of 300 bars. Unlike electric systems, it ensures optimal airbag inflation within seconds during an avalanche and remains effective under high pressure.

Without electronics, our airbag is always ready for use thanks to reliable and easy-to-store energy, easy to maintain, and its rechargeable cartridge contains no toxic or controversial materials.
