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.
Please Note: The F52 in Multicam is only available with the ALICE frame. They do not come with and are not compatible with the Intex ll frame.
Dimensional Shipping Weight = 21 lbs. Actual Weight = 7.2 lbs.
Similar to the F4 Terminator, the Jackhammer has a sleeve between the back interior wall and the main frame panel, with a horseshoe zipper in the top flap. MOLLE compatible webbing inside the sleeve is arranged to allow you to hang any of our scabbards, which allows you to carry heavy man-portable weapons nearest your center of gravity. In combination with the Intex ll frame, this is a really nice way to carry heavy weapons (or lighter ones for that matter).
The Jackhammer's interior features start with an amply sized storm collar, which allows you to over-stuff the pack. Next, a back wall radio pocket with second pocket and cinch-strap, two plastic-mesh zippered see-into pockets, a ring of translucent pockets around the bottom tier of the pack, and a generous matrix of MOLLE compatible webbing on the inside of the front door.
