Coming straight out of the future, the Black Diamond JetForce Halo 28 SM Airbag Pack is revolutionizing the industry, with the first ever rechargeable airbag that inflates using a fan in about 4 seconds. Benefits over traditional canister style airbags are evident no canister means they are great for travelling and practicing. With 4 deployments per charge, understanding the deployment of your airbag has never been easier. Plus, the JetForce Halo 28 is an awesome pack in and of itself. A dedicated avy tools pocket and ice axe carry, along with a diagonal ski carry that does not inhibit airbag deployment make the Black Diamond JetForce Halo 28 SM Airbag Pack a force to be reckoned with.
