The Slide Over Bottle Coolie is happy to bring beautiful branding and open-cell insulation together at last. Each coolie offers maximum water absorption and easily stretches to fit 12oz bottle shapes.
Open cell information: Open cell foam absorbs water. The ability to absorb condensation from cans and bottles is one of the benefits this product affords when used as a beverage insulator. The foam is made from 100% polyester which results in low costs.
