I got one of the Solo packs a couple of weeks ago. I loaded it up with two bags of water softener salt (80 pounds total) and took it out for a hike. I am very pleased with it so far.

To be honest, I was a little skeptical that a pack this light could be comfortable with a heavy load, but the frame is very ridgid and the suspension fits my body type well.

I will take it on several backpack trips this spring and summer and if it holds up, I will use it on a Dall sheep hunt in AK in August.

FWIW, mine weighs 3.62 pounds on my digital scale, so the advertised weight is very close.

The first great thing is to find yourself and for that you need solitude and contemplation. I can tell you deliverance will not come from the rushing noisy centers of civilization. It will come from the lonely places. Fridtjof Nansen
