I've purchased this when it was available here earlier this summer. I used it for a motorcycle tour of Wisconsin's state parks. I'm 6 foot even, 210-220 pounds and this bag fits pretty well. I don't think the specs page does justice to the customizability of the fit. You can move the straps laterally on the bars to accommodate wider shoulders. The frame itself is also extendable, the distance from the bottom of the sack to the hip belt can be changed. When properly adjusted for me it is almost at the maximum extension. Also, I keep it packed with clothes, hammock, sleeping bag (strapped to the bottom), tools, first aid/personal hygiene, food, water, and a stove sufficient that I can up and go camping for 2-3 days at the drop of a hat. It really has done well for me this summer.
Edit: I used it as it was shipped to me once, it made my back hurt pretty bad Turns out it was set for somebody much smaller than me, after adjusting it's been great.
