Review by Facebook User on Nov. 12, 2009
Light weight, hydration sleeve separate from main compartment, & integrated rain cover.
The pack doesn't have a frame or a frame sheet, mine developed an uncomfortable roll in the back panel after a couple of months. I still use the back for backpacking and use a sleeping pad to eliminate the roll in the back panel.
I just picked up a Gregory Z35R. It looks great, but haven't used it enough to recommend it yet
