After the enthusiastic response that we received for our J51 Warhammer, we decided to carry on in this new direction, and built the Jackhammer. The F52 has a blend of some of the most popular features of our tactical packs: combined top-loading and barn door front-loading access, interior organizers including back wall PRC-117 radio compartment, PALS/MOLLE compatible webbing, full-length tubular side pockets, an LP-1 compatible top flap, a built-in rain cover, and more. This combination makes a really great, robust, highly organized mid-sized pack.
Like the Warhammer, the Jackhammer 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.
Our original approach to embedding the frame inside the structure of the pack creates a super quiet, tough, body-riding pack. 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, comfortable and well ventilated field pack.
We first built the F52 Jackhammer 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 Jackhmmer’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.
By itself, the F52 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 to expand the system.
To finish off your pack system, you can add any of our weapons carriers. Our scabbards will attach to the built in zippered compartment that run along the backside of the pack.
1000 denier nylon exterior.
Please Note: because the F52’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.
