Review on 🏃 RevereSport Waterproof iPhone 11 Running Armband with Bonus Pockets for Keys, Cash, and Credit Cards. Phone Arm Holder for Sports, Gym Workouts, and Exercise (Ideal Fit for Small to Large Arms) by Tsuyoshi Tendencies

It's designed for very small (female) hands unless you use an extension that adds 6" in length and then only fits huge bodybuilder arms , there is no golden mean for full-size guns. Since the bracelet has no elastic, it always feels too loose or too tight. To top it off, it's aimed at the iPhoneX that I have, but it fits and moves fairly loosely in the case, so it's clearly a one-size-fits-all.
