This held everything I needed for a 3-month backpacking trip through SE Asia. I found it to be a very comfortable pack that distributed the weight evenly across my small frame (I'm 5'5") and it held up well to downpours in Laos, dusty roads in Cambodia, and everything in between.
I've also used this pack for camping trips and it holds my tent, sleeping pad, clothes, and accessories with room to spare. I just need to pick up a compact sleeping bag.
