It is a fairly big backpack. The sewings are poorly made, with badly cut fabric (which prejudicates the openin and closing of zipers). The zipers look quite alright, as do the multiple stripes. I like the interior, it looks sturdy. Overall, the backpack is not as good as I expected BUT it is a good deal for the price I paid.
Straps were not sewed straight making them not work. Belly strap is too big even when fully tight and I'm a 32 waist. Design has many flaws. For the price I guess it's good enough but I expected more and have bought other similar bags at better success
The one bag (black) has terrible defects. It does not even close properly on the main top flap due to the elastic being sewn so tight. The side straps are 4 inches sewed lower than the buckles as well. Disappointment for the one bag. The other bag is good and has no issues. I will contact seller to resolve the problem.
