Bought as a gift - I think he'll love it.
I think I've had this thing in my pocket for 8-16 hours a day, every day, since probably late 2017. The stitching and elastic hold up like new, the material has taken on a slightly darker tone and a gloss from being in my pocket and exposed to sweat for that time period. I use it to keep essentials on hand at all times in a single consistent spot. I generally keep my flashlight, multitool, and folding knife in my right pocket, but my left gets this. Inside I have some basic emergency supplies, Ibuprofen, Benadryl, Dayquil, caffeine tablets, gauze pads, nitrile gloves, nail clippers, antacids, Celox, butterfly closures, a couple adhesive bandages, chap stick, a lighter, and a chamois for my glasses. I would sooner leave my phone at home than forget this.
Over the years I haven't had a single thread pull loose, the zipper has functioned flawlessly, the elastic hasn't begun to break down, and there has been no unusual wear or marking of any kind.
