While one of Osprey's larger capacity offerings, to be honest it's a little smaller than I anticipated.  Not small enough for carry-on, but not far from it either.  I purchased this specifically for a trip to the Dominican Republic, where we stayed for 6 days  Typical for me, I probably needed 4-5 change of clothes (since we were in swimsuits most of the day) and I probably brought 10.  I used packing cubes though and was able to get a lot into this bag.  Much more than I thought.  I had 3 pairs of shoes, which takes up a lot of room.  I had an old pair of tennis shoes, for an excursion (I left them there) and some Sperry's and then some water shoes in this bag.

The quality is top notch, which I would expect from Osprey and a little higher dollar piece of luggage.  When I originally started looking at these, I wanted the backpack or perhaps the Sojourn.  After a lot of research, I opted for the Ozone, thinking I would make my carry-on my backpack, which I did and it worked out well.  Plus the Sojourn was just too much money for the amount of traveling I do.

The handle works well.  The wheels are the best I've used.  There are only two...and don't allow you to pull it any direction, like you can with the 4 wheeled bags.  But that's OK with me.  The compression straps are a great addition, although I think they could use another one on the interior.  The one interior strap seems a bit "off" in it's placement and didn't cross my packing cubes very well.  I chose the black color because it was cheaper, but I would suggest another color if you want to more easily identify your luggage at the baggage claim.

The only "con" I can think of, is that the handle mechanism seems to take a lot of space up inside the back.  Again, you can fit an amazing amount of stuff into this bag, but that handle mechanism is quite stiff and bulky and does take up some room.

As checked baggage, I can't think of anything better.  the pockets were enough to fit everything I wanted to in.  I used the mesh pocket on the top flap to put "used" or "dirty" clothes into.  All in all, great piece of luggage I would recommend.
