6'2" 230lbs large size
I have the above measurements and pack size. This pack has performed well for me. The only time I had a problem was day 2 of the Inca Trail. I didn't adjust the straps properly in the morning and one of the shoulder straps really dug in hard all day afterwards. I tried correcting it at lunchtime, but it was already sore at that point. Other than that, which is partially my fault, I've had no problems. I think the only minus is it's lacking the bottom zip the 65 has. I have the 08 and before version of this pack.
Additionally be careful as 09 brings a new model with several additional features:
- air cavity is vented on the side, this allows it to be smaller and gives you a easier load/unload.
- has a quick stow and go system for storing trekking poles on the go (possibly other things).
- the water bottle pockes on the side are angled so you don't have to remove the pack to get in/out of them with a little practice.
If any of those features sound good to you, you might want to compare the money you save buying this model on sale vs. holding out for the newer version.
