The J51 Warhammer is built around Eberlestock's innovative Intex-II frame, which gives the benefits of better body contour-fitting ergonomics, closer-to-body load carriage, and a bottom cargo shelf, in an intelligently designed package. Because the frame is fully wrapped in the structure of the pack, more along the lines of an internal frame than an external frame, we've eliminated frame noise, and built an exceptionally comfortable and well ventilated pack. The Warhammer is an off-shoot of our popular J79 Skycrane II, but has more generous side/main butterfly compartments, so in effect the Warhammer has more stand-alone capacity. However, the products are very similar in function, and use many of the same components. The Skycrane II system includes the G1 and LP1 packs, which can be purchased separately when building a J51-based pack.

By itself, the J51 is a great stand-alone pack, with ample 3-day-class storage and two pockets sized for 70 oz/ 2-liter hydration bladders (sold separately). It doesn't need any other components, depending on your personal preference. But you can do some great things by mixing and matching accessories and other bags to expand the system. In effect, you can build any pack you might conceivably need by pairing the J51 with some of our other products. To get a super-organized front-loading pack, you can zip a G1 Little Brother into the J51s load bay. Or for simpler bulk storage, choose a J2SD or J3SD Spike Duffel... or a combination of any two of these; you can attach two duffels at the same time, or you can embed the G1 pack into the interior of the pack by zipping a duffel outboard of it. Then, you can attach the LP1 FannyTop Go-bag to the J51s top panel. These practical options in a relatively lightweight and extremely efficient system make this a fun, versatile, and highly effective backpack. Note, for adding hydration, WX2L or WXP3L, we recommend installation in either the LP1 or G1 packs, or the A3SB Saddle Bags.

To finish off your pack system, you can add any of our weapons carriers. Our scabbards will attach to the generous MOLLE/PALS type webbing that adorns the load bay, and panels zip away from the top and bottom flaps in order to allow for the protrusion of long guns.


*NEW FOR 2021

The 2021 Warhammer now has baffles that allow more room when carrying a scabbard or pack on the frame.  When you're not carrying a scabbard the baffles can be zipped closed which gives you a more compact fit.

Sturdy and versatile.

Thing is a tank, and I can pretty much pack any day pack inside the folding wings. I will use it for deployment and travel.

Well thought out

This back was well thought out as it leaves room to customize your load and detach for a short range ruck.

J51 Warhammer with the G1 little brother

Absolutely amazing pack! I bought the J51 with the G1 Little Brother and as a combination the packs together are beyond what I expected storage wise and quality. I’ve been doing 5 to 7 mile rucks with 80 pounds inside, both packs combined as well as each by themselves and they’ve met every condition I’ve thrown them into and they’ve come out still in perfect condition the J51 really holds the weight with the Intex-II frame. I especially love the detachable HBSS hip belt which makes it easy for my to detach the G1 and take the HBSS off the J51 to attach it to the G1 for reconnaissance. I’m a Sniper Team Leader and will be in the field for a month so I’ll update my review after getting the packs in the field and utilize them.

in integrity

My last dealing with these people You did make those offers to me , never was there a disclaimer they could not be combined or stacked. You offered me a unilateral contract which was complete after I got the first text on my phone. I was offered and accepted in Arizona and may choose as a choice of law and venue to deal with those disagreement. 

More important , that long drawn out commercial you run about your bosses integrity and honor bla bla bla is just BS?

I'm asking to send this to him and he can explain why keeping his word is in sink with that commercial about how I learned integrity.......

Fits everything.

I have the J51 Warhammer (Tan) along with the Spike duffel (Tan) and G1 Little Brother (Multicam). It fits literally everything. Full Sleep system and full ECWCS system fit into the spike duffel and side pouches, as well as extra boots and extra uniforms. Leaving the Little Brother to hold all operational gear. Currently packed is poncho liner (wobbie), CLS/blowout kit, small tool kit, extra batteries, kestrel, binos, hygiene kit, munchies and some other stuff I'm probably forgetting. 65lbs as pictured.
