Review on 📱 RevereSport Waterproof Running Armband for Phone with Case On - Compatible with iPhone 13/12/11/8/7/XR/XS/Max/Plus & Samsung S21/S20/S10/S9/Plus/Ultra & More - Designed for Otterbox, Lifeproof, and more by Black Holstead

First of all, my Samsung Galaxy S10e with Otterbox fits in with plenty of space! Mind you, the seller recommended the medium for my phone and I bought the large. If you want a tighter fit so your phone doesn't move. Cool, take Wednesday. There is a velcro closure at the top. So unless you do tight flips, I don't foresee your phone falling out even if you get a larger size. Two different arm straps in case you have muscular arms. ;) Item arrived overnight.<<UPDATE>>I used it for several workouts. And I have no complaints. With a wrist strap extender, I can be flexible about what I wear. When I train indoors, it easily fits on my shirt/arm. When working outdoors I usually wear multiple layers and use a belt extender to pull on a long sleeve tank top + shirt + jacket + hoodie. Definitely a pro I hadn't thought of before. I had no problems with a large body. It doesn't pinch and doesn't give me any trouble walking. That being said, if you're concerned about your phone having enough room and space. grow up. The card slot is perfect. If you are in a hotel and need to keep your room key there or if your gym has a membership card. I could fit about two or three cards there. 10/10 so far.
