Y MountainLine Safeback Lid for Daypack 40

Safeback SBX is an active air supply system designed to keep avalanche and tree well victims breathing during burial. The system uses the air in the snowpack as the victim’s air supply, continuously pumping it up through an intake in the backpack and delivering it through hoses in the shoulder straps. The system is activated using a T-shaped handle on the shoulder strap and supplies breathable air for 90 minutes.

Snow is composed of two key ingredients: ice and air. But for avalanche victims, much of the air in the snowpack isn't available to breathe. Safeback SBX is designed to continuously retrieve fresh air from the snowpack surrounding the user's backpack, delivering it up to their breathing area. This supplies them with fresh air to inhale and pushes the CO2 they exhale away from their face.

ATTENTION! To ensure optimal function in a critical situation, please read the accompanying user manual carefully. To install the SBX unit correct on backpack, please follow our instructional video.

Nylon 66 with Dyneema ripstop. Together with our partners Dong Jin and DSM Dyneema, we spent 2.5 years developing a perfectly balanced ripstop fabric. Made with a blend of carefully selected Nylon 66 and Black Dyneema yarns, with PFAS free water repellency. The Dyneema ripstop represents a perfect combination of low weight/cost and high tear-/tensile-/abrasion resistance.

Fabric is bluesign® APPROVED.

PFAS free DWR treatment: Avoiding harmful chemicals for water-repellent finishing.

All our products marked with the PFAS-free logo use a water repellent treatment that is free of PFAS substances.

PFAS (Per- and polyfluoroalkyl substances) is a group of more than 10.000 substances also known as fluorocarbons. They build up in nature as they do not degrade. In greater concentrations, they are proven to pose a hazard to both human health and the environment.

PFAS has been common to use for the so-called “Durable Water Repellent” finish (DWR): It means that water bounces off the surface rather than being absorbed by the fabric and making it wet. Using PFAS has been an effective treatment to achieve a durable water repellency for waterproof fabrics, but also other applications like ski waxes or food packaging.

Since these chemicals have shown to be harmful for both people and the environment, Bergans is working to phase out all fabrics containing PFAS finish and replace with more environmentally friendly, PFAS-free treatments. All the membranes we use are already free for PFAS. You can read more on PFAS and how we work to eliminate these.

A significant part of the challenge of using alternatives to PFAS lies in the lower durability of these water repellent solutions. That means that using a waterproof garment with a PFAS-free finishing requires you to re-impregnate these more often than before, to achieve a good water-repellent functionality also over time and after many washes. Anyhow, please always consider where and when it’s necessary to reduce environmental impact.
