J34 Just One Backpack - Amazing!!

I just purchased the Eberlestock J34 Just One backpack and used it on both an elk and white tail hunt in Idaho. The pack is perfect in every way! I love how versatile it is. I can use it on day hunts, as well as multi-day overnights, and it performs amazing for hauling out meat. Super comfortable, it makes the whole hunting experience even more enjoyable! Buy it!

Just One.. more

I have a few Eberlestock packs. I absolutely love them. Just took the J34 for its first hunt (grouse/bear) in Northern Ontario. As expected, pack fit great, carried the weight better than expected, and of course had that great spot for either my rifle or shotgun as I had both with me on the hunt. Couldn't be happier with the design, construction, quality and service.

Great pack just wish that the hydration bladder pocket was larger.. My 300 win mag fits nicely in the scabbard…

J34 Just One pack

Quality should be the name.. pack is outstanding in construction and comfort… the padding is far better than hoped for.. the sleeve fits a Remington 700 with leupold mark 5 like a glove.. plenty of for packing everything you need for a weekend scouting trip and then some.. looking forward to packing this on my mule deer hunt this year in the Ruby mountains

It’s a great pack I recommend putting the same bag that’s attached on top of the pack on the bottom also. Just need a few more storage pouches.

Great pack

Only problem I've had is the water reservoir section does not fit most of my bladders. It's very narrow.

Great idea, fatal flaws

I recently purchased an Eberlestock J34 pack and, while I was impressed with the overall construction of the pack, several design shortcomings led me to ultimately reject and return it.

I was willing to overlook the badly designed top flap, with zippers that seem placed to allow things to fall out when opened, and a single strap (rather than the standard two) that offers little in the way of torsional stability to the top as it sits on the main body of the pack. I was also frustrated by the fact that the horizontal load compression straps go around the outside of the exterior pockets, rendering them inaccessible without undoing the compression straps. This also makes it impossible to tighten the straps without crushing what may be in those pockets. The final straw for me came when I loaded it up with 47 pounds of gear in preparation for a summer scouting trip. The presence of the built-in (empty) scabbard, which in theory is a great idea, made it impossible to adequately tighten the load against the pack frame and suspension system. The short fabric loops that are in place for this purpose do not allow the pack to tighten fully against your back, leaving you with an unsecured load. It was unacceptable to me with less than 50 pounds in it; I can’t imagine trying to haul out 85 pounds of meat with this suspension. I’ve carried 100-pound packs on mountaineering expeditions, so I know it’s possible to design a pack that will carry that weight solidly. This, unfortunately, is not one of those, IMHO. Probably great for light loads, but for backcountry deer hunting, I opted for a MR Marshall.

From Bird hunting to Moose hunting

The options and capabilities on this pack are fantastic if you purchase a few more items.
I personally think the zip in panel orange on one side camo on the other is a must and should be included.
The spike duffel is a great choice as well.
This pack is ruggedly built and will last for generations.

Perhaps the only downside to it is its weight if you are hunting in high altitudes and or steep terrain this pack is not for you.

But for everything else from Bird hunting to Moose hunting it is superior.

I highly recommend the J34
