About the REACTOR airbag system :
The Reactor airbag system has been developed to prioritise the three following criteria: lightweight, practicality and comfort. This backpack has a double airbag with a total capacity of 150 litres combined with a double inflation system. The shape and positioning of the airbags are designed to maximise upwards motion during an avalanche.
The inflation system is designed to be compact and lightweight (680g), while optimising performance in real life situations. All of these innovations have been the objective of three patenting applications. The Reactor system can be detached from the backpack and transferred to another compatible bag.
Please note : while this bag is equipped with the Reactor system, it is without the trigger cartridge (gas bottle).
