The Black Diamond JetForce 35L Pro Pack is the latest rendition of Black Diamond’s excellent line of battery powered airbag avalanche packs. Unlike traditional cannister powered packs, the JetForce system is rechargeable and allows for multiple deployments, giving you no drawback practice sessions and eliminating any moment of doubt that might prevent you from deploying the bag in a 50/50 scenario. Additionally, the battery powered system is easy to travel with, and lighter and more durable than ever. The pack itself is streamlined and perfected for backcountry use, and has a modular design to allow you to swap out for different volume pack faces depending on the needs of the day.
