With options for bottles, cans, or a velcro option for any size beverage, these koozies are great quality and keep drinks insulated. The koozies are made from a 100% polyester topped-neoprene (white) with open cell polyurethane foam back lining (black). They are printed and then sewn so that the printed image is edge-to-edge seamlessly applied with no creases or voids in the image. The bottle koozie has an easy to use black zipper with a round zipper pull to make it easy to take on and off.
