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.

Awesome product

Just One, Great Name

Wither you just need a day hunting pack or a three day hiking pack. This will do it. It modular design so you can add more storage, add a Supper Spike duffle (2500 cubic inch storage) to the J34. It zips right in still have room to carry out the rear hocks and meat of a deer…You even have a rifle scabbed to carry your rifle in. Its you to you as to how much you want to Carr y or can carry I should say with this pack. Just don’t get carried away end end up turtle on your back..

Almost perfect

What first drew me to the J34 was its modularity. I wasn’t disappointed. I can easily transition from using it as a daypack to a travel bag to a small field pack. And not just any field pack, but one where I can stow my scoped Remington 700 BDL or Mini-14 and still have them easily accessible. That said, the J34’s rifle sleeve is too narrow to fully swallow an AR-15 with optic; I couldn’t get one into the sleeve past the pistol grip, even with just an Eotech mounted. And although I could just about squeeze a Rem 700 SPS with overmolded stock, sling and 44mm scope into the sleeve, I couldn’t get it back out without first taking the pack off. Most traditionally stocked hunting rifles with a reasonably sized scope should fit perfectly. Still, I recommend Eberlestock do away with the hard to reach, small zippered pockets that sit opposite the sleeve and use the extra real estate to widen the top and middle portions of the sleeve to expand the universe of rifles that can be toted. All in all, an almost perfect, cleverly modular pack that will see many years of use.
