Where can I get one of those really good Adidas string bags?

Hi, I am looking for an Adidas string bag, but one that is really good. I saw a girl with one that had two zippers in the front, and it was really good quality. Know where I can get one? If so, how much will it roughly cost? Thank you very much!|||you can get them from the adidas store at a mall or one the website. you can also get them at acadamy
