The durability seems to be good. As a Marine Corps veteran, I've carried quite a few spider/tactical style slingshots, so I know a good one when I see one. I believe these straps are intentionally slightly larger so you can trim the end to the length you want, like I did, as shown in the picture above. I also burned the ends with a torch after cutting them to keep them from fraying. Stretch enough, not too much. The belt is easy to put on from the inside out. The closure is very quick. The only minor downside to this strap is that you have to undo the buckle and remove the strap to remove the strap as the buckle doesn't go through most loops. However, this is very easy to do by simply pulling on the cut end of the belt to open the buckle as shown in the second image. Overall a great belt. I bought two packs and will definitely be buying more.
