Running Pouch Waist Bag This waist pouch bag is very lightweight and compact, but made of stretchy fabric that expands depending on what you put in it, allowing you to carry a smartphone, keys, etc. You can adjust the belt to fit your body perfectly, so it won't get in the way. I used it about 5 times while running, but I no longer use it, so I'm giving it away. Although it has been used a few times, there is a part where the rubber has stretched, possibly due to aging. I don't think it will affect usage, but please check the photos before purchasing. Color: Black Zipper part: Pink
