I have the Chinesium version in the 50L version. The design of the backpack is excellent, very common sense and well formatted. I had to get a smaller sleeping bag so that i could carry it with the paracord webbing at the top but aside from that it carries everything well. The top pocket (under the cord) holds a lot of things, I keep my folding saw in there, knife, a headlamp, a hanging lamp, all sorts of stuff.

There are the everyday pockets that are necessary - no infuriating oversights - and then more little pockets here and there which become useful over time.
What I like is that there always seems to be enough room at the top of the main compartment for the 1 last thing I need, which is a multi-compartment bag of useful things.

It's quite adjustable for making it a comfortable carry but I lack experience in exactly how ergonomic a backpack can be. It's easy to get a system going with this format and I'm glad I cheaped out and bought the aliexpress version because it was only $60 in your money.

>picrel: a fabric chair that allows you to almost completely lean back. I lean it up against said backpack and have full back support. Crafty chinese I tell ya, and all so astonishingly cheap.
