I bought this to replace my old bag bag-to-back Targus whose zipper had half passed away, yet guaranteed for life! I must say that I had drunk beyond reason. Zippers, it is usually the weak point of bag-to-back. It understand many inner and outer pockets. I will pref 2 zipped side pockets instead of one zipper and one open (single thread). there is a padded and protected computer and a tablet inside pocket compartment. Convenient, big, solid in appearance, simple and elegant, proper discounted price. Short but good!
