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

Very nice pack. Lots of room.

Well Built, Practical and Comfortable

I like how practical this pack is. With the Spike Camp Duffel it has more than enough room to carry supplies in for four to five days or carry meat out. I have not tried it without the duffel yet, and I don't see why it wouldn't work. Very versatile and adjustable.

Great pack, a little heavy

I've only put about 5 miles on this pack so far so take this review with a grain of salt. The pack is very sturdy; I'd have absolutely no qualms about weighing it down with 100 pounds or more. I really love the fact that I can draw my gun from the pack without removing it. You need to be a bit limber but it's totally doable and I feel quite smooth with that motion already. Definitely don't but a hydration pack that's bigger than 2L as that's all that that particular compartment will hold. I haven't found a good place to store the hydration hose when not in use so that's a bit of a downside for now. The pack is quite heavy which is unfortunate knowing that I try to cut ounces on all of my gear including gun, sleeping bag, sleeping pad, camp stove, etc. It feels a bit like taking a step backwards in that department. The large rain cover fits the pack well. I purchased the duffel along with this pack as per Eberlestock's suggestion but I'm not quite sure how to combine these items in the most efficient way. So far, I'm not sure how much I gain by having that piece to go with it. Lastly, know that if you're buying a pack where there are 2 compartments between your back and the main pocket, anything you carry in that main pocket is going to put a bit more strain on your back than with another backpack where that weight can be pulled in closer to your back. That said, I feel like it's a fair trade-off to have your rifle protected and off of your shoulder while still within reach. I'm 6'1" 175lbs and hardly had to adjust the pack at all.
