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 Carlos Block

This bandage is a bargain. With two Velcro attachment points and an optional extension strap for larger hands, it's likely to fit almost any hand size. Thanks to the slightly stretchy quality of the material, it stays snug. My phone fits in pretty well, even with a thin case (which is nice as it feels like it'll at least keep an extra layer of protection in case it's dropped). The audio/charging/headphone ports seem to be well matched to the iPhone 11. The additional key/credit card/ID slots are also a great addition. Haven't tried using it in the rain yet so can't comment on that. Material waterproof. Otherwise, this is a great option for those looking for an affordable fitness band for their iPhone 11.
