Review on 📱 Innens Cell Phone Running Armband for iPhone 13 11 Pro 11 XS XR 8, Galaxy S20 S10 S9: Water-Resistant Sports Phone Holder with Adjustable Band and Earphone Jack, Ideal for Hiking, Biking, and Walking - 6inch (Black) by Brian Whitmore

The product description specifically states that it is suitable for Samsung Galaxy 9S+; but that's all you can do with both hands on the zipper. And it seems like the seams of the case are about to burst. It would be impossible to remove/replace the phone while it is being carried. It would probably even be impossible to unzip/receive the sleeve. Also, I measured carefully to make sure my arm was no longer than 16 inches; but the strap does not stretch enough to put on alone and is too tight to wear comfortably.
