Review on Zokrintz Running Resistant Runners Adjustable by Ashwin Chauhan

My son has a small medical device that needs to stay within 20 feet of him at all times so I brought this belt with pockets so he can easily carry his device for not quite 30 days and the Zipper began to separate from the edge. In the picture I put pink stickers between the zipper teeth so you can see them better. I will try another style from another company but unfortunately many of them have this problem with the zipper.
