Fantastic construction and quality. Very comprehensive and well thought out design. It may not be for everyone or every situation, but it has definitely found a home amongst the rest of my packs.

I have never had a pack that didn’t hurt my shoulders until I found eberlestock. My Just One pack has over 400 miles on it. I have not had this pack out yet but I’m expecting the same quality. Don’t hesitate buying any of there pack!

Is mostly going to be used for camping trips and hiking. But I am a slimmer then average guy and with 40-60lbs, including a plate carrier with 12lbs in plates it fits much more comfortably then my g3 phantom. But thats for my small bones and plate use with this pack is last resort.

Nothing but good things to say about this rig. Great quality, versatile, intelligent design… why don’t you have one yet?

The quality of this pack is everything and more than I expected from all that I had read about and the reviews I have seen.
I can't wait for the G1 little brother to come back in stock and add options and components to its versatility. Then my adventure starts, and the test of me and my pack begins.

Despite settling for the multicam due to the other colors being out of stock, I am very pleased with the versatility, comfort, and quality of this ruck.

Being a former Soldier in the U.S Army, I can fully appreciate the thought that went into making this pack what it is; simultaneously comfortable and utilitarian.

I’m able to use it by itself or incorporate my EDC (Switchblade inside the zip-on duffel) into the Warhammer. I can even strap in the Switchblade bag between the expanding “wings” of the bag and then zip on the duffel on top of all THAT. Should I ever need that much room, of course.

It took me several weeks to come to the conclusion that I wanted, needed, and craved a bag like the Warhammer. It’s the pickup truck of bags. The versatility is outstanding. And for it to be comfortable is mind blowing.

My only complaint is that I couldn’t find a decent video review except by some dude in what looked like the Philippines. Couldn’t understand a word, but he really showed off the bag. Shout out to that guy.

Although the the videos on the Eberlestock website are of a very high production value, they don’t show much at all. I would have chosen the Warhammer a lot sooner if Eberlestock had much more information in their videos. Hell, even more detailed pictures would have helped. This goes for all of their products, btw.

Regardless, take it from me. This bag is tits. No wonder it is sold out in all colors except multicam.

I purchased a complete Warhammer system including the J51, the Little Brother, the Fanny Pack Lid, the Spike Duffel, and the weapon scabbard. I ended up returning the entire system as it wasn't great for my needs.

I found that despite having an overall amazing capacity the individual pockets of the J51 and the Little Brother couldn't really fit all my mission critical gear as they were each a bit too small or limited. Likewise a consideration is that when you flare the batwing pouches out for the G1 or duffel you had better make sure you put equal weight in each pack. Not a review here of the G1 but as others have noted thee so-called hydration bladder sleeves don't actually fit the dimension of nearly any bladder including the Source ones Eberlestock sells. As for the Fanny pack it's great but would be better with quick release buckles.

So awesome design and craftsmanship but not suitable for me personlly.

Love the pack. Still waiting on the military green little brother. Need it ASAP.

I also purchased the little brother and it is amazing to lighten the load as a WSL in the Army. On leaders recons I’m able to assist my light infantry guys to take out extra ammo without carrying full ruck. The modularity is amazing!!

Recently was in the field for weeks with this pack (J51 Warhammer + Little brother) and was able to comfortable live out of it. I had my overnight items like my tent and sleeping bag in the side pouches and everything I may need throughout the day in the center (Little Brother Pack) this included ACH (helmet) and IOTV (tactical vest; although it was notable difficult to fit however nothing else I know of can do this). Easily the most versatile pack I have ever had and based on the quality so far I expect to use it indefinitely.
