I bought this pack to replace my old day pack. First thing to comment on is the fit. I put the pack on first thing w/o a load, and the shoulder straps fit great! the sternum strap is well placed. The waist belt snugs the bottom of the pack to your back nice and tight. would like to have the waist strap wider as to accommodate a clip-on anything (knife, GPS, Radio, iPhone) but it gets its intended job done perfectly. I decided to load it up to see how it feels with weight. It can hold a ton, more then you might need for a day hike. It will be perfect for when me and the GF head out, I can hold all our stuff. The front pockets hold a ton of gear as well, and keeps it organized. There is a gear loop, and lash points on the outside. a handle on the top on outside pocket are convenient as well.
My only negative (hence the 4 stars) thing would probably be the two side mesh pockets. My Nalgene bottles don't make a perfect fit. But once the pack is strapped on, they stay put due to the fact that the waist belt pulls the pockets tight. I tested it by bending over with both 1L full and they didn't move.
All in all, a decent pack for under $100. I will be field testing it this weekend. i would recommend it.
