I used this to hold my smartphone while running. The belt has stretched a bit, but it's still usable with no stains, tears, or damage. [Product Details] SPIbelt Basic Basic size that can hold a smartphone. Despite its smart and compact size, it has a surprisingly large capacity thanks to the stretch material. It can even hold a 350ml plastic bottle! It fits snugly against the body, and the contents of the bag also fit snugly. The belt is adjustable from both sides and made of rubber, so it fits perfectly to the body, eliminating the annoying bouncing and movement of items inside the bag that are common with waist bags, and it won't hinder your movement. It's perfect for running, and it's also great for travel as it can hold a passport. This size is popular and convenient for festivals and everyday use.
