Compared to my old REI pack of Boy Scout years past, this thing feels like wearing pillows. Breathes well, sits well, and just does an overall good job. Do be advised that the hydration pockets are not elastic and only hold up to a 2L bladder. Don't be like me and buy a 3L bladder without reading the specs.
The one change I've made is replacing the waist strap buckle with a Cobra buckle, but that's just personal preference. I did have a thread come loose on the elastic sternum strap after about 15mi of use (loaded to about 50lbs), but haven't had any more problems since. Looking forward to adding the Little Brother to this setup in the near-ish future!
I need to pack out with several different units. Each has different gear requirements. To support this, I need a bag that could pack a lot while also being configurable for the mission at hand. I bought the Warhammer, the Little Big Top, and the large waterproof bag.
I am able to zip the waterproof bag into the main compartment, load that with items that shouldn't get wet, and then also zip the LBT on the secondary load points. The LBT fits with its own straps and waist belt attached...for more room you can also remove them. Using the straps that come with the Warhammer I am able to cinch everything down nice and tight. The pack is amazingly comfortable and easy to manage.
For other mission sets I need to zip in my fire duffel or my rescue duffle. The Warhammer is able to gobble up those bags too. The horizontal straps are able to reach around these gear bags and keep them in place. The duffel bags are sitting on the frame and therefore unable to slip down over time. The vertical straps for these duffels will need the available extension straps.
To carry less gear in this configuration I can also leave the drybag at home or leave the LBT at home. Both zip directly into the main compartment without any problem at all.
And for an even smaller load I can just zip the two side bags that come with the Warhammer together.
And when the Warhammer is too much or a framed pack in general is too much I now have a Little Big Top to carry a fair amount of gear.
I have been a 5.11 bag guy forever. I have done many events and missions with 5.11. But I finally hit my limit which needed me to upgrade to Eberlestock equipment. Now having trained with and touched Eberlestock gear...I can see swapping my entire family out to Eberlestock backpacks. Top-notch quality bags. I will be singing this company praise for some time to come.
CA Fish and Wildlife builds in the Mojave Preserve quickly showed me I needed a pack that was both modular and had the ability to help carry heavy loads. The J51 seemed like the winner, especially when I saw the pictures of it being used to carry a jerry can. I can now say that it has handled a fifty pound Honda generator and a long list of tools. The adjustability allows me to balance the load and maintain comfort. The only draw back to this pack is that it weights so much empty. But given some of the loads it has had to carry, I can forgive that. In fact, I bought a second pack for my son.
Definitely haul 80lbs in this thing every other day for at least 5 miles and its the most comfortable thing ever. Built tough, and I don’t feel like I’m gonna break something picking it up or strapping it in. Just ordered the G1 little buddy to go with it for more organization and possibly the scabbard later
Great quality, love this pack. Lots of modular options. You may want to get a spiked duffel with it to get more space, for a multi-day outing. I like to go out for at least 3 days at a time, any season. I have plenty of room for a shelter, hammock, wool blanket, woobie, ifak, camp fuel, some food and additional supplies. However if hauling additional food and clothing for longer trips get the duffel. Also i am about 5'11" 165lbs 40 in chest and the pack fits perfect. However i feel like it may feel small on some one much larger as I am at the top of the ladder system. Still highly recommend. Shipping was also quick. I will order again.
