Worst backpack material ever, I regret trusting this brand for quality, I'm beyond disappointed. Inner material of this backpack started falling off from the first day we used it for school, after first was it became a disaster, looks like we've used it for months but it's only been 2/3 weeks. Now I have to go back to the shops and buy another backpack, not even after the 1st half of the year, what an inconvenience. Very annoyed about this.
