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.

Bloody good pack

I bought the J34 Just One pack because I have had a
GS05 Gunslinger for about 16 years now and could not fault it. The Gunslinger is getting a bit old in the tooth now and needs a new harness and waist belt and also showing a fair bit of wear. I decided to go for the J34 Jut One because of it's similarities with the GS05 and the fact that it expands out to 4600 c.i whereas the GS05 is only 3600 c, i. No doubt that the J34 will be just as phenomenal as the GS05 if not better. 😍👍

Worth the wait

Order this for an upcoming Wyoming deer hunt. I am very pleased with the quality and comfort. Can’t wait to fill my tag.

Almost Awesome

I purchased this pack because its versatility. This pack is small enough to carry as a day pack, and large enough to carry EVERYTHING (and nearly any size in between). The negative: An AR15 style rifle will not properly fit the the weapon carry pocket. Half of the width of the pack was taken up by pockets, eliminating the ability to carry a rifle which has both mag/pistol grip and optic.

Just One with the big boy belt

I am very happy with the just one Dry earth that I received a few weeks ago. I did order the large belt and it is a game changer (I’m 6’2 245). Love the spike duffel addition and I am able to pack everything I need for a spike camp or a 3 day weekend trip. Pack Is high quality and I have put some serious tension on the straps with no issue. Solid pack!
