Mounted the C20M packbag onto my ALICE frame and used my V2 Shoulder Harness and Prairie Belt. Rigged up some compression straps and docked my Tarahumara to it. Then added the HSGI Alipad I just got to the frame. Loaded the ruck up to ~40lbs. I got to test this set-up out today for a couple hours with what I would consider a medium load. Feels very comfortable and I feel that the Alipad augmented the HPG harness well. Fitting it to the existing harness wasn't hard at all. I would say that this set-up would be more in line for a heavier load, say up to the 60lb. range. For a lighter load, I can remove the Alipad pretty easily and just run the HPG suspension by itself. Really pleased with how it turned out and love the C20M for its simplicity and bomb-proof construction. I'll pay my hard-earned money for quality American products like this anyday. The Tara is working great as a compression piece along with the straps I rigged up (I found an on-line source for G-hooks, etc.). Now that my knee is feeling better post-surgery, this pack will be the one I will use as part of my program to get back out into the hills and put in some miles. I have become more impressed with the Hill People Gear products I have every time I use them! You just cannot beat the versatility, modularity, and craftsmanship that shines in these products! Evan & Scot....you guys definitely have the magic when it comes to hard-use backcountry gear design. Hope you never change the recipe. I'm so happy with this C20M and suspension, I have ordered a DEI 1606 AC frame for it. A pack this nice deserves a new frame!
The pockets on the Alipad are meant for hydration bladders (they have a small hole at the top), or for soft items...maybe light rain gear.
Used an additional pair of straps and G-hooks to run from the Tara to the frame. These, along with the side compression straps make nice tool holders for an axe or my alpenstock.
The Alipad backpad is pretty comfy, I have to say. It married up to the HPG suspension without issue.
