The newest member of the Just One family is at the pinnacle of backpack design. With all of the features of our other Just Ones, the Dragonfly raises the bar, featuring a high tech suspension system, a huge range of adjustability, and more patented and proprietary features than any hunting pack made. A full slate of premium features includes a full framesheet, which augments the internal aluminum stays to give a very stable load bearing platform, and a fully adjustable shoulder harness and beefy #10 zippers. If you're thinking about a Just One pack, and feel that you'd be most comfortable with a firmer platform for carrying a heavy load, or if the vertically adjustable shoulder strap attachments appeal to you, choose a J107.
