We first built the J51 Warhammer around the ALICE frame, a tried and true pack frame. Using the frame as a core structure, we developed an entirely new style of pack that has amazing utility and versatility. It takes advantage of the ALICE's compact size, and incorporates features and qualities that have made Eberlestock packs famous. Now, after proving the concept, we've replaced the ALICE frame with Eberlestock's innovative Intex-II frame, and have thereby gained the benefits of better body contour fitting ergonomics, closer-to-body load carriage, a bottom cargo shelf, and a whopping 1.3 lbs of weight removed from the pack. The latter stems from the fact that the ALICE was a frame for a more primitive design, and had far more metal that the Warhammer's internal-frame style requires; the Intex II provides just as much stability and load bearing strength, in a much more 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 J51's 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 J51's 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, 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.

We have a newly redesigned Intex II frame. The new frame has the same rigidity, ultralight and tough construction, with a shortened base shelf. This frame will be rolling out as the new standard for the Warhammer pack. In the meantime, we have the packs available with three different frame styles [Intex II long-shelf (shown in picture), Intex II short-shelf, and legacy ALICE frames]; color and frame combinations will vary depending on current inventory. If you aren't certain which you'd prefer, or if you can't find the one you're looking for on our website, feel free to call or write to our customer service and we'll tell you about the currently available options.
Please Note: because the J51's Intex II is made to fit the footprint of the ALICE frame, it's wider than our other styles, and it is not interchangeable with the AG2 Gossamer frames.
