Last January, I spent a month backpacking around the south island of New Zealand. I needed something light, moderately large, and and comfortable. This pack fit the bill perfectly! The ventilation system is top-notch, the waste straps and shoulder straps are light and breathable. Love the pockets, especially in the waste straps. Overall, great pack. Buy it.
