The bag is not as heavy duty as I thought it would be. It's not super thin, but also not thick. But the biggest problem is that it's somewhat useless as a backpack. The top of the straps are attached to the bag too low, which means the bag does not sit well or comfortably on the back. But the worst part is, the buckles used on the shoulder straps are not the correct type of buckles for a shoulder strap because the straps slide completely out of the buckle. Therefore, the backpack shoulder straps cannot even be used.
