It's a good backpack, but it's really not really strong. Although immediately after receiving mail, two bottles were loaded in the store for two litres of soda water And two bottles of one and a half gallons of minerals, plus a different product per kilogram. And eight kilos were good, the stitches weren't cracked: the kids in school would be great. It's not critical, but it's not critical, I just burned them with a lighter. a hole under usb is needed to insert a cable that goes with the backpack, to charge your gadgets from the head of the bank. The name of the brand in the backpack is embroidery, and the label is full of paint. I usually change my backpacks every year, and I think it's enough for that time. My recommendations.
