I bought one of the Koolies some years ago and still use it everyday. Just decided to get my Hubby one and another for myself. They cover most all of the water bottle which is perfect. They all are so cute with the monogram. I have the solid and poke a dot Koolie and they are adorable and work great. As I said I use mine everyday and have had the original Koolie for over 3 years now and it looks the same when I first got it. They are very durable and hold up well which is the main reason for purchasing extras. Thank you for such a great product.
