Just received this little backpack.  It is smaller and not as sturdy as it appears online.  This would not be useful for a larger man because of the way it fits on the upper part of the back.  I am 5'7" female average frame and I debated about keeping it because the shoulder straps are snug, but I'm going to give it a try.  I think it will be fine for light hiking trips.  I have a shoulder problem, so I can't tolerate a heavy pack.  The material is not thick, but zippers look good and straps seem sturdy.  Will not hold a tall water bottle. The mesh should have come up higher. It will fold up nicely and not take up too much room in a suitcase.
