Mechanical airbag backpack -
The Airbag Flex Pro 40+ backpack from Arva is an airbag pack designed for mountain outings requiring capacity, modularity, and organisation.
Its expandable volume from 40 to 50 litres allows you to adjust the available space according to the equipment carried. The ARVA REACTOR 2.0 system, integrated into the Flex Frame, features two 75-litre airbags and weighs only 650 g. The Flex Pro 40+ Cover offers dual access to the main compartment from the top and back, as well as a complete separation between the volume and the base to facilitate interventions with reduced weight. Its Daisy Chain system allows for adjustable carrying, while the attachments accommodate skis, snowboard, snowshoes, and up to two ice axes.
The Flex Frame combines a padded rigid back, 3D-FIT shoulder straps, and an ergonomic belt for stable carrying. Dedicated safety pocket, five additional pockets, gear holder, and hydration compatibility make organisation easier. Made from recycled ripstop fabric and water-resistant, the Airbag Flex Pro 40+ backpack supports demanding adventures with versatility and efficiency.
