This thing is my favorite pack.
I have the internal-frame Sting jn DPM, which is all nice, rigid, and supported, but really a lot of pack. Those are for extensive loads that totally don't contribute contribute your knee, hip, and back injuries.
Rather than run the zip packs / panels, I used the convenient 1" compression straps and their spacing to lash on these Savotta 4L rocket pouches (if you do this, use the slots in the zip panels by the back to get a nice, tight anchor) and flipped the flimsy belt around to mount Dutch double magazine pouches and GPs by Nixieworks and 8942NW.
There is a slip for a stiffener/pad, and the little foam rectangle does enough one a swagman roll and bivvie are stuffed into the bottom half of the main compartment.
The liner is peeling, but dry bags exist for a reason.
This is my winter pack, and it holds my sustainment load with the modifications shown. I use it with my Nixieworks LFR after removing everything from the buttpack. The LFR holds the ammo, water, IFAK, gloves, a headlamp, and my knife and multitool.
Packed right, it's very comfortable. On its own, it's a great summer pack unless you run hot like I do. It will hold plenty of food and water + a summer weight bivvie for an overnight whole remaining slim.
