Arva Reactor Flex Pro 24L Airbag Backpack

The Arva Reactor Flex Pro 24L Airbag Backpack is perhaps the perfect backpack for backcountry skiing. The 24L size is ideal for carrying everything you need for an all-day excursion without getting in the way, and the design is ergonomic and sensibly equipped with easy access to your avy gear. If you need more capacity for a longer trip, you can zip off the cover and replace it with any of Arva s other Flex Tech covers. And most importantly, it comes equipped with Arva s super lightweight REACTOR dual airbag system, which just might save your life. Aside from proper training, good partners, and carrying a beacon, shovel, and a probe, having an airbag backpack is one of the best things you can do to increase your chances of survival in the event that things get much scarier than intended.

Compartment140D x 210D Cordura Polyamide Ripstop HR


REACTOR SystemWith a total airbag capacity of 150 L (2 x 75 L each), combined with a dual inflation system, the REACTOR insists on security and reliability. The airbag's shape and positioning have been designed to maximize upward mobility in an avalanche. The inflation system is more efficient, compact, and lighter, while at the same time addressing the demands of real case situations. You also have the possibility to take the REACTOR system out of your backpack and transfer it into another compatible REACTOR backpack.

Quattro Snow-Shield Air Intakes4 air intakes boost the inflation system with a high air flow protected from the snow.

Rotating and Locking HandleThe compact retracted handle prevents inadvertent activation.

The Flex Frame consists of the frame, back panel, shoulder straps, and Arva REACTOR avalanche airbag system. The zip off Flex Cover consists of gear storage space, and comes in different sizes depending on your capacity needs.

Product Details

Beacon Features

Arva Evo5 TransceiverArva's fully featured, high end digital transceiver. Small, dependable, and easy to use.

Design and ErgonomicsThe design and ergonomics of the device were taken into account from the very beginning of the EVO5's development to make handling simple and intuitive. A 3 position slider, an extra large screen and a central marking button make it easy to operate the device during the search.

Small But PowerfulDespite its compact size, the latest addition to the ARVA range offers performance worthy of a great one. 50m of search bandwidth, marking function and interference management for smartphones and other electronic devices are available. The automatic return to emission in the event of an over avalanche also ensures an increased level of safety. The group-check and U-turn indication complete the functionalities to facilitate the use of the device.

Miniature DVAThe EVO5 is the smallest DVA ever designed by the Arva brand. With only 11cm in height and 7cm in width, it is one of the most compact detectors on the market. Its size and light weight of 170g allow it to be forgotten without neglecting performance in an emergency situation.

Carrying OptionsThe EVO5 comes with a carrying strap and a leash that slides into a pocket while keeping a solid attachment around the waist. A holster for traditional porting is available as an option.

50M Search BandwidthBandwith corresponds to the size the area scanned by the searching device. The device’s search area increases as bandwidth increases. This criterion is often used to compare beacon performance.

Interference ManagementInterference management maximizes the device’s performance in search mode in an environment overrun by electromagnetic interference. To accomplish this, the device in search mode automatically reduces the bandwidth and ignores all other frequencies to focus solely on the beacon being tracked. This function can be deactivated by the user.

Automatic Switch Back to EmissionDuring a search, in the event of a secondary avalanche, the return to transmit function allows the device to automatically switch back to transmit mode. This switch is activated either by timer after a certain period of time of user inactivity, or by motion detector after a certain amount of time where the device has not moved. Configure these timeframes in your beacon’s settings menu.
