Strong fabric and stitch. Heavy duty, great quality just like the other pouch I got from this shop. Measurments are as follows. (Can for scale)
15 inches long
7 inches tall
5 inches wide in the main pocket, and the front pocket adds at least another 3.
It is the kind of bag that easily compresses into itself if there's not much in it, taking up less room. And at the same time, you can pack a lot of stuff in there if you want to! Either way it fits nicely on a belt, or over the shoulder. Love it.
