Review on Premium Non-Slip Sweatproof Samsung Galaxy S21+/S20+/S10+/S9+/S8+ Running Armband - Secure Sports Phone Holder with Key/Headphone Slots | Fits Phones up to 6.7” | Ideal for Jogging, Gym by April Russell

I have a Galaxy S20+ and I have a case with a small profile and it fits perfectly in a bracelet. It is comfortable to wear and easy to adjust. It's flexible enough that it doesn't cause discomfort when you need to bend or strain your arm and muscles. The phone slides into and out of the case without sticking. The material absorbs moisture a little when you sweat a little, but not much. It does exactly what it was designed to do and it does it very well. If you own one of the listed Galaxy phones and are looking for a armband phone mount, this is a good choice.
