I purchased this backpack for use on a 3 day trip through the White Mountains in New Hampshire. Since I have back issues, I was looking for something that was lightweight yet big enough to carry what I needed for three days. The adjustable chest and waist straps allow the backpack to fit perfectly to sit higher up on my back with no pressure on my lower back. The ventilated back allowed enough airflow to keep my back dry. I did not find the hip belt pockets as easily accessible as I hoped. Maybe if I lost a few inches around my waist it would help. LOL Overall, I was very happy with the purchase and hope to hike many more mountains with it. I am a 5' 3", 53 year old female and the x-small/small fit perfectly.
This is an excellent back pack! One of the best features is the structure of this pack, which includes an air flow ventilation system - created by having a gap between your back and the actual back part of the pack; what keeps the pack off of your back is a taught panel of mesh which lays right on your back for comfort and shock absorbency. I also love the contouring of the shoulder and hips, which fits exactly on top of my hips and helps reduce the weight on my shoulders a significant amount; I was not able to get this with any unisex or men's version back packs. The shoulder straps do not get really sweaty for me either, although I have not worn it with a very light tank yet so I may have to edit if this changes.
As far as storage goes: the first zipper portion pictured (with the Osprey logo on it) is a small pouch suitable for keys or a few small objects. The middle zipper is the main interior of the back pack, which is fairly large but not the biggest available. The...
I really wanted to like this pack for hiking - it seemed so practical and comfortable, but in the end I decided it was far too small for me. I had a 3L Platypus hydration bladder which was really really difficult to get in and out of the designated compartment, while empty. I have to imagine that working with it while full would have been nearly impossible. Also, by the time it's full, I don't know what else you'd be able to fit into this pack other than very few emergency supplies. Not sure a rain jacket or fleece, or more than a couple snacks would fit in this thing. I personally like to carry a small bag of emergency supplies (multitool, water filter, etc), warm layer, gloves, food, as a minimum, and once you fill the bladder I am thinking it would have been TIGHT and I would not be able to fit anything else! I also wanted to be able to use it on occasion for travel and it was quite small for those purposes as well. I am curious as to what all these other reviewers were...
