This Pack is available in Dry Earth or Rock Camo The J51 Warhammer is an offshoot of our popular J79 Skycrane II.  It id s little shorter, but has more generous side/main butterfly compartments, so in effect the basic Warhammer has more stand-alone capacity than the main pack of the Skycrane II.  The two products are very similar in function, and use many of the same components. Whereas the Skycrane II system includes the G1 and LP1 packs, these can be purchased separately when building a J51-based pack.
	The Warhammer is built around the U.S. military's beloved ALICE, a tried and true pack frame. Using the frame as a core structure, we've developed an entirely new style of pack that has amazing utility and versatility. It takes advantage of the ALICE's compact size, and take-anything-you-can-throw-at-it toughness, and incorporates features and qualities that have made Eberlestock packs famous. 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 quiet riding, comfortable and well ventilated pack.
By itself, the J51 is a great stand-alone pack, with ample 3-day-class storage and two pockets sized for 100 oz/ 3-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.
