The redesigned PIEPS Jetforce 2.0 avalanche airbag pack is the latest progression of our innovative Jetforce Technology that is lighter, smaller and now includes Bluetooth capabilities. Pieps's revolutionary JetForce Technology is still rechargeable and travel-friendly, and features multiple deployments, with automatic deflation to create an air pocket, and has an automated self-diagnosis, but now the updated, lower-profile system is positioned lower, which improves the way the pack carries. With the addition of Bluetooth connectivity, you can update the software directly through the PIEPS app on your smartphone, as well as personalize settings. The 10-liter pack features a dedicated avy-tool pocket and plenty of storage for extra layers, water and additional gear, plus the pack is modular, giving you the option of purchasing a 25-liter, or 35-liter booster pack, which you can attach to the JetForce system for more versatility. The pack's ice-tool attachment secures your essential gear, while the tuck-away ski attachment system allows the airbag to deploy when skis are attached. The deploy trigger features status lights and can be switched to either the left or right
