The FLEX COVER PRO 40+ lets you customize the volume, design, and functionality of your ARVA REACTOR airbag backpack for long and demanding missions.

Thanks to its roll-top construction, it offers an expandable capacity from 40 to 50 L, making it ideal for rescue professionals operating in remote backcountry terrain with substantial equipment.

Its robust design features complete separation between the main compartment and the FLEX FRAME base, with a modular internal divider to isolate equipment or reduce weight depending on the mission. The pack opens flat like a suitcase, providing fast, unrestricted access to all your gear.

Like the other PRO models, it is equipped for both lateral and diagonal ski carry and is built to withstand intensive use season after season.

WARNING! The FLEX COVER PRO 40+ cannot be used on its own. It must be paired with a FLEX FRAME base to be fully operational.

Separate compartment

The PRO 40+ FLEX features complete separation between the main compartment and the FLEX FRAME base. An internal divider lets you isolate your gear, create an additional compartment, or lighten your load by keeping only the airbag base when maximum freedom of movement is required. The pack opens flat like a suitcase, providing fast, unrestricted access to all your equipment.
Weather protection

When snow and rain demand maximum protection, the pack's water-repellent fabrics and water-resistant zippers provide an effective barrier against the harshest conditions.
Optimized handling

A padded side handle makes it easy to grab, carry, or load the pack, whether you're placing it in a vehicle, boarding a chairlift, or moving it around a storage area. A thoughtful detail that makes every movement easier, even while wearing gloves.
Gear loop on the waist belt

Some tools should always remain within easy reach. That's why the FLEX BASE features a dedicated ice axe holder and a gear loop for quickly attaching essential equipment. A simple, reliable system designed for fast action in the field.
Ski carry — Your choice

Every professional has their own preferences. The pack supports both diagonal and lateral (A-Frame) ski carry. Choose maximum stability or the fastest setup depending on the terrain and your skis.
Internal pockets

Dedicated internal compartments keep your equipment organized and secure, ensuring quick access and efficient organization during every mission.
3D-FIT

The 3D-FIT system provides fast, intuitive adjustment for optimal comfort, regardless of your body shape or personal preferences. Simply select S, M, or L to instantly adjust the back length, shoulder strap length, and REACTOR handle position for a perfect ergonomic fit.

1 SINGLE SYSTEM FOR ALL OUR RANGES OF AIRBAG BACKPACKS

Two airbags are safer than one!

The ultimate inflation system

Two airbags are safer than one!

We developed Flex technology to allow you to change the carrying capacity of your ARVA REACTOR avalanche airbag backpack in just a few seconds based on need.

Choose an additional FLEX COVER element to create the pack that best suits your needs.
The lightest avalanche airbag system on the market

Weighing in at just 650 g, our ARVA REACTOR 2.0 airbag system is the lightest airbag system on the market across all categories.

Made in France, the avalanche REACTOR Airbag System is designed exclusively for ARVA backpacks.

We oversee the entire process, from design to production, to provide you with the highest level of performance and safety.
Positioning is important

The most powerful system on the market, its compact size, and position in the backpack guarantee uncompromising balance and safety.

The shape of our airbag protects your head and optimizes lift in an avalanche.

The position of the airbags increases the surface area. It also helps the body return to the surface, and the airbag volume plays an important role in pulling the body upwards.
The ultimate inflation system

As 60% of airbag backpack releases occur when the skier is caught in an avalanche, it is essential to have a system that can inflate under stress.
