It is actually much larger than it appears, and when you open it to take something (probably because the main zipper is sewn too low), there is a constant risk of something else falling. Otherwise, the material quality is average, it has a large capacity, and the strap is big and thick. It has three compartments: the main one, an inner one with a net, and a small external one. I'm not crazy about it, I wouldn't buy it again
