Black Diamond Jetforce Halo 28L Avalance Airbag for sale.  350.00 OBO. I used it for 3 seasons.  I'v pulled it less that 10 times, only for preseason testing and for fun.  Never had to pull it outside.  Original booklet, international plug adapters, and chargers.  Works A-OKAY.  Some minor, cosmetic wear on shoulder strap from a tree.  Holla.
