Review on 2-Pack Waterproof Fanny Pack Pouch for Men & Women - Dry Bag with Adjustable Waist Strap, Water Resistant - Ideal for Water Sports, Boating, Snorkeling, Swimming - Protect Your Valuables by Derrick Milkie

My use: swimming and snorkeling. I bought this for my Samsung Galaxy 10+ with Otterbox Defender and Pop Socket on the back. None of the other smaller cases would fit in this phone unless I had to remove the Otterbox, which is a ridiculous suggestion. I didn't want a huge bag. This bag measures 8.5" x 6" when closed. (Some of the others on this scope are an inch larger on either side.) My phone fits perfectly, leaving room for keys, money, etc. I first tested it underwater with a tissue and notepad for half an hour. Then I checked my phone. It will float so I had to submerge the bag with a pot filled with water. Both times the things in the bag were dry. The 3 zip lock system worked well. I was able to use the apps on my phone in either pocket: fairly easy in the transparent black pocket, but I had a hard time reading emails through the opaque orange pocket. I would not recommend Orange if you intend to use the phone in a case. I couldn't use the camera in either case (I have a protective glass but don't know if that was the reason). I didn't buy it to use my camera, just to take my valuables out to sea and not worry about leaving them on the beach so it serves my purpose. The strap was well made and fit comfortably.
