The top priority of the Arva Reactor avalanche backpacks are safety and reliability! The Reactor 40 includes an advanced avalanche airbag of a total volume of 150 litres (2 x 75 L), as well as a dual inflating system. This construction allows the reactor to grant a so-called emergency reserve boost and that even after a severe crash and mechanical damage on one side. The position of the airbag as well as its shape are optimised in a way that it consumes as little space as possible in the backpack and that with a total weight of only 2.15 kg of which 790 g is the airbag system itself and thus, it can still be considered lightweight! Not included in the delivery are simply the adequate gas cartridge from Arva, along with the extremely light Carbon fibre cylinder (310 g) or alternatively the robust Steel cylinder (450 g).
Part of the Reactor 40 - the biggest backpack of its collection - are several useful details among others a separate front compartment for individual LVS-equipment, a Top Loader Lid compartment for all objects that need to be easily accessible such as a useful ski goggle pocket. Additionally, it has an extra map compartment as well as removable or rather retractable straps and holders for skis (diagonal), snowboard and ice pickle. The practical Twist Hook multiple purpose mounting system for all kinds of additional equipment rounds off the whole. The carrier system is equipped with an adjustable 3D Fit Technology, which is an anatomical preformed waist belt; the Touring Back System, which serves as a back ventilation; as well as a safety belt in the crotch, which keeps the backpack in worst cases on the body. Thus, the Reactor 40 climbs up - with its material reinforcements made out of Cordura - to the top models among avalanche backpacks. It is ideal for multiple days ski tours, free riders and snowboarders, who do not only need a lot of space but also do not want to do without the additional protection of an avalanche airbag. """
