I'm selling this because I don't use it anymore. I've used it for running a few times. It's a good size for running with a smartphone. Please only purchase if you understand that it is a used item. Description from online search: This is a band-type pouch made of stretchy material that fits the body and doesn't shake easily. It can store large smartphones and has excellent storage capacity with front and back pockets. Reflective material is used to improve visibility at night. It features a lightweight, thin construction.
