I bought this product to match my 21 inch zebra heys exotic spinners and it does it has an elastic band that keeps it attached to the handle of the spinner. It worked well except the times I was going over a curb, then it tended to spin around and I had to reposition it, but no big deal. The only other thing that I am not so fond of is the handles on it aren't really flexible, I thought they would move out of the way but they are fixed in that position. Just makes zipping it up a little more awkward. All in all a great product.
