I've owned this pack for a few months now, and have taken it out on four treks -- three weekenders, and a five night trek in the Colorado Rockies. A drawstring can be pulled tight to create two compartments, or loosened for one large compartment (I prefer two compartments).
Fully loaded the pack rides comfortably on the hips, and does not pull on the shoulders. The pass-through sleeves, which are behind the side pockets, allow you easily carry tent poles or similar close to the pack. Outfitted with several compression straps, your gear will remain in place throughout your trek.
I did not expect to ever use the detachable lid, but we dropped our backpacks at the treeline, and the lumbar-pack/lid came in handy on a summit assault. I have the Mountainsmith rain cover which was used for one day. As expected, all of my gear remained dry. Folks that tried to use trash bags did not fair so well.
This is a very economical and versatile pack. I have no regrets purchasing this pack.
