Featuring the latest progression of Black Diamond'sinnovative JetForce Technology, the new JetForce Pro avalanche airbag with PIEPS technology is lighter, smaller and now features Bluetooth capabilities. Thisrevolutionary 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 25-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 10-liter, 35-liter, and 25-liter splitboard 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 shoulder strap and you can adjust the height for personal preference. The hip belt also features a redesigned leg-loop strap, which is now retractable and features a carabiner clip for quick attachment to the hip belt.
