Huh…
The pack in the link below reminded me of this old thread, so I thought I would update…

Looks like it might even work with a conically rolled pad (slightly rainbow-ish when the pad is flat, MYOG). But… that belt doesn’t look like it will take loading very well, which would be the main reason to carry your pad that way. And no water carry options…
$283 (US) seems high, given you still need to buy the liner bag. Part of the cost is that the yen seems to have made a small comeback since I last looked at KS Ultralight packs.
(Though no one asked, I will say that the Equinox Katahdin pack works well in this style, putting up to 30 lbs on my hips. I did about 2/3 of the Florida trail with it. However, I’ve moved on from this idea, and I will not be testing the linked pack, I don’t think. I have since gone completely frameless and use an inflatable pad (I ditched cooking, and got a lighter shelter)… Did the AT with a Zimmerbuilt Quickstep… Now I’m way off topic, but… FWIW… I loved this pack… just a few small tears in the pack fabric near where the mesh connects near the top of the pack, on both sides. I guess I wasn’t very careful stuffing things into the front pocket. I taped it up, inside and out, and it held without further damage. So, the tape mainly served to maintain water resistance, it seems. I had it loaded up to 26 (?) pounds a few times, just after a resupply. Bearable at that weight, but not comfortable. For me, under 20 was fine. No padding in the shoulder straps, just the mesh. But they are angled and shaped nicely, for me at least. I added a sternum strap, and a small sheet of thin foam as padding, inside the pack. I did quite a bit of jogging… Strapped tight, it worked great. The roll-top/tie-downs work well for compressing the pack. I liked not having a hipbelt. Less restricted twisting motion, more air in the torso. Water resistance: all day rain will yield a tiny bit of rain inside the pack. I didn’t use a liner, just stuff sacks. No problems. It was especially dry this year, however, at least for the sobos. Really impressed with the quickstep overall.)
