Great bag. I was able to carry my DSLR and some essentials while hiking. It's not "slashproof" but it is sturdy and I felt that my items were safe in it. It did pretty well during a rainstorm. I love the water bottle pocket and the ability to switch what side you carry it.
** pack bigger things on the bottom since it gets much smaller on top.
When it was jam packed the zipper split open but fixed itself when I emptied the bag.
