This seems to be a very well thought out pack. Used with 3/4-length crazy creek chair (as a pack frame, seat, and 3/4-length pad) for recent 2-day hike. Using this (or any other sleeping pad) prevents using the bladder pocket, but just dropped the included bladder into the body- not ideal, but workable. External mesh and zippered waist belt pockets great, though the side mesh pockets were a bit high to reach while wearing the pack. I would have liked to see an external sleeve for tent poles, but that's not a deal breaker. Very light and the fabric itself seems durable. Will be keeping an eye on where compression straps are attached, though- seem a little under built there. All in all- pretty good so far.
