i'm no expert on packs, this is the first and only pack i've ever had, but i have no complaints with it. it was perfect for a 10 hour hike. i had enough room for a sandwich and some cliff bars, a first aid kit and a light jacket. plenty of water for 10 hours. very comfortable and light weight. it is good looking as well. some dude even yelled back that he liked my pack as he ran past me down the trail.
