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.

Amazing pack. Love the products.

I honestly don't know yet to rate your product due to the fact it is for my boyfriend on our anniversary which is on May 15. Once he opens it and tells me how excited he is than I can rate your product.

Well-made hunting backpack.

I was in need of a new backpack for an out of state hunt later this year. My brother Beau is a guide in the Blue Mountains and said this was one of the best packs he had ever owned. With his advice and only trying it briefly so far, I agree. This pack is roomy, comfortable and appears to be well made. The backpack was shipped quickly and directly to my home. I hope to send photos of my successful hunts later this year. Thanks for a great product.

Truly a “one-stop shop”

I’m a pretty intense researcher, so I worried that the decision on a hunting pack could be a nightmare. My hunting partners both run the M5 RMEF Team Elk and love it, while I’ve hunted several seasons using my Osprey camping rig. I wanted something lower profile than the M5 (internal frame and not camouflage) but that would still have the capacity to haul major weight and have the fantastic Eberlestock rifle scabbard (my previous pack could carry a lot but there wasn’t a great way to secure my rifle when packing out). In the end the J34 fit the bill perfectly. I compared the weight, features, capacities and capabilities to every other manufacturer I could find; without exception the competitions’ offerings were all more expensive, less feature-rich and lacked Eberlestock’s proven history and tactical pedigree. I hunt every season from spring turkey to late season elk in the high Rockies and look forward to using this pack for those chases. It hasn’t been out on a hunt yet but I’ve been rucking with it daily and so far it carries like a dream. I’ve been loading 45# in it without issue and can tell it’s going to be harder to find the right weights to put in it than to max out this bad boy. The weight carries close in to your body and the adjustability of the pack is great, especially for someone with scoliosis who requires some wonky fitting to get the weight to ride correctly. The only issue is that the hydration sleeve (as mentioned in several other reviews) doesn’t fit a 3L bladder. Fortunately I read that and bought the 2L, which fits perfectly and is honestly a good amount of water, especially when supplemented with a quart or two of hydration mix in bottles. Overall it’s a killer pack; build quality and materials are top-notch and the fit and finish made it worth every penny.
