Received my fanny pack ( not crazy about name - just kidding! ) and it fits perfectly. It adjusts perfectly to my size which is average ( size 10 ). I am able to put my iPhone 8S and a small 8oz bottle of water which I really need living in the Deep South. Louisianas good day is a temperature of 95.  The bag is bright and colorful. It is a little large but I needed that for my iPhone. Very pleased with my purchase!
