The materials are good for the price. I actually thought it was a little poor quality, but it turned out really well. I'm traveling with my iPad Pro 12.9" and it fits perfectly, 2 laptops in and a few other things and everything fits great. The zippers are of good quality and the fact that the large flap is held in place by magnets rather than velcro , really good touch, just what I was looking for, velcro wears out too quickly.
