We have been talking about this ruck in other threads, but wanted to start one just for this ruck, because I think there's is some truly ground-breaking work going on here. For those of you that are interesting in long range patrolling, for security purposes, the subject comes up of how you intend to carry your load out. When we talk about military applications, it's usually a choice between a short back ruck and "battle belt" system, or, a long back ruck and chest rig (possibly PC) system. A good example of the former is a Large ALICE, with battle belt and suspenders, and the latter would be a MR 6500, with a chest rig and/or a plate carrier.
And there have been some interesting developments in both categories. For example, combining an upgraded ALICE bag, with a DE 1606 frame, and a custom suspension (such as a DE "mountain" harness). With a Brit style belt kit. Or a MR ruck, with a Crye JPC, and custom micro chest rig.
But then 22 Foxtrot introduced us to the Crossfire DG-16. What they have done here is phenomenal. Essentially they have figured out how to have both a short back and long back ruck, in the same package, by adjusting/modifying the suspension system, on a frame that acts like both an internal, and external; it has a nice "hollow", that will accept a back plate, or it will provide a nice air gap, ala ALICE.
After having dabbled with this, on and off, for over 30 years, I took one look at this, and knew they had done it. Someone finally figured out how to make a ruck, for military applications, that will not only work with belt kit, but also with chest rigs, AND body armor. Done and dusted.
I truly believe this will be a game-changer. They have set the new standard for military ruck design. I just pulled the trigger for their frame and suspension, in multicam. Which is available for purchase, separately. It will work with any ALICE compatible bag, although I plan on removing any ALICE sleeve and rigging it as they do their bags, via "Yib-Yab" tabs (as seen on Jarhead or Molle rucks). Perhaps not necessary for all, but I want a more solid interface between bag, frame, and suspension.
BTW their bag bears much resemblance to MR, and is a thing of beauty. However, I am going in another direction, essentially keeping it as light as possible. So I will be working on a new bag to complete my system.
