This item is an insulated jacket for your bottle. Its made of neoprene, which is what wet suits are made of. It fits the bottle perfectly because of the zipper.

* Prevents bottle from sweating

* Protects the bottle from scratches and dents.
* Made from insulating neoprene
* Keeps liquid cold or hot longer.

Others charge $14.99 for their insulated totes, ours is much better as we use a zipper and they use inexpensive velcro. Ours covers more of the bottle so it insulates better also. At only $6.95 you can't go wrong.
