The Blue Widow is a distilled version of our J-type packs. It's essentially a Dragonfly with the scabbard layer removed. The main vertical pockets and utility expansion compartment are attached directly to the main frame panel, creating a pack that protrudes a relatively shallow amount relative to the wearer's body. The pack performs beautifully under a wide range of load conditions. We added a larger Flex Chassis which can fold forward for use as a seat. And because we think that scabbards and packs go together, we made it so that you can add one if you need it. Like our other J-type packs, the JP9 Blue Widow can be expanded by adding one of our J-type duffel bag accessories.
