This is the latest version of the pack that started a gear revolution, the legendary Just One.  As in, "if you're going to own just one hunting pack, own a Just One."  It's extremely versatile and comes with the hallmark patented features that make Eberlestock packs unique. 

Starting at an ultra-compact 2300 c.i, the built-in Cam Expansion system expands it to 4600 c.i. Add a Super Spike Duffel, and you get a 7500 c.i load hauler (Spike Duffels sold separately).  The J34 features a built-in hunting rifle-sized Backscabbard, Cam Expansion, streamlined shape, vertically adjustable torso length, waterproof zippers, a high-visibility interior, deep "3D" ventilated padding, scabbard drainage and cleanout access. Strategically placed Padlock Webbing (MOLLE) allows you to mount accessories, and makes excellent perimeter lash points.
