After much research I decided to buy this bag as a carry-on option. I really wish it was closer to 40L in capacity since the 30L was a bit too small and 46L too big. Once I pack my hiking boots or large DSLR camera space is limited. My biggest complaint is the location of the chest strap on females. It is placed directed over the breast which crushes the breast. Not above or below the breast. WHY??? This seems like such a basic design consideration, how did a major brand of Osprey make this huge mistake for females? For this one reason I have to return the bag. The straps are a bit uncomfortable at times but otherwise the bag is well made and attractive.
