Review on 🏖️ JOTO Waterproof Waist Pack with Strap - Waterproof Case Dry Bag Pouch for Beach, Swimming, Boating, and Fishing - Protect Cellphone, Camera, Cash, Wallet, Passport from Water and Sand (Black) by Roy Boone

I wore it on my beach day while on a cruise. It was great to bring money, phone and key card. at the beach walk. BUT, as soon as you hit the water, the bag fills with air and floats on the surface of the water (while the strap is securely attached to your waist). It is very embarrassing and embarrassing to have this bag floating in front of you. You can't push it down, it just bounces back up. Now, if you go deeper into the water, it will be submerged, but it will still fill with air like a balloon and float at your belly level. I won't wear it in the water anymore.
