I have this back pack for few month now. I can say it has good quality of the material and design, especially I like the front lock, but zipper is terrible - it covered with some kind of fabric or protection, I don't know exactly what is it, which started to rip off just after couple of weeks I started to use it. Now It looks old because of the zipper. I had to buy new one,. this time I bought Case Logic which looks more neat and I hope will be more practical.
