This pack got me started on Osprey packs and I'll never look anywhere else. Every time I load it up I'm surprised at how much I can carry without feeling burdened or weighed down. It's a bit more complicated than a regular backpack and It does NEED* to be adjusted and sized properly but once it is and you have the proper distribution of weight into your pelvis it's an amazing pack. The anti-gravity system and really all of Osprey's packs with the mesh air flow areas are a godsend. I live in Hong Kong where you can pour sweat just waiting for the bus sometimes and regular backpacks just soak through immediately. The mesh suspension systems eliminate that problem completely. I do wish there was a bit more for organisation in the top compartment. Some dividers would help a lot as the main difficulty I have is how much things tend to bounce around and shift so I can't find the things I need while other things are falling out. The belt pocket zippers are a bit tricky but this can be a good thing in cities, especially on my little talon 22, you can store things in them without fear of pickpockets easily accessing them.
