Reactor Airbag
For the past 15 years, through own team and partners, ARVA has played an important role in the development, production, and support of avalanche airbag systems. Studying and applying hundreds of actual accident reports, ARVA made the choice to innovate own specific product in this field. After two years of research and development, ARVA is proud to present the one of the lightest, most functional, and reliable dual airbag systems on the market.

Reactor System
The inflation system has been designed to offer a compact and lightweight product (790g), while optimizing performance in real life situations. All these innovations have been the subject of 3 patent applications. It is possible to detach the Reactor system from the backpack and transfer it to another Reactor compatible bag.


HQ Cylinders
The cylinders are made with high-quality materials and are designed to withstand over 300 bars (4351 psi) of internal pressure. The steel cylinders comply with Directive 2010/35/EU in Europe and with DOC/TC regulations in North America. The carbon cylinders comply with ISO 11119-3 standards. The cylinders are single-use and can only be refilled by Arva.
