Has the features and durability of more expensive packs. Could have larger water bottle pockets. I found the pack very comfortable.
Loaded the bag up to about 50 lbs for a week-long hike through the Weminuch wilderness. Pack did absolutely amazing. Had such a good time, which was largely due to the pack. It was easy to load and easier to carry. The front zip makes it easy to retrieve items from the middle of the pack without having to unpack the whole bag.
This back pack is really nice. The only down side is it only has in big pocket. The previous pack I had had an additional pocket on the front so I could quickly access the things I used most. Smart water bottles stay in the pockets well with the strap going across them.
