I need a backpack to go shopping because I hate bags! In several other backpacks that were not always very favorable, then the institution or institutions plan always sometime above where they are sewn, because the shopping is sometimes quite difficult. This model is extremely robust, that it makes the thick water-repellent material, with zippers that make me hope me a long time. He is perfectly finished, nowhere loose a little thread, everything closes without jamming, the carriers are softly padded and you get good 2 shopping bags transported. Back-friendly. The design also pleases me well! a super backpack in which you have some time. The manufacturer gives a lifetime warranty on him !!! Strong buy recommendation!
