Comments about Gregory Gregory Z 55 Pack:
This pack is very comfortable and adjusts very nicely. The adjustable hip belt makes it all the more personalized to your fit. The air flow across your back is very nice as well. Took this pack for a weekend trip on the AT, did 38 miles and had everything I needed. This pack is ideal for loads from 20-30 pounds but anything more you would have to utilize the exterior pockets, though there is still enough room for all that you may need. The pack is not in the ultralight family but the weight of the pack as opposed to the comfort level for me was a good decision. My favorite feature was the zipper along the side of the main compartment that allowed me to get my jacket without having to undo any straps. This pack is a sound investment with many happy returns.
