The new Pulltex cooler bags combines the efficiency of the Pulltex regular coolers and new esthetic trends. It is covered with white, highly resistant tissue that makes it look elegant and fashionable, while the inner part of the cooler is covered with a black nylon material.

The bag is closed with a security cord in its upper part which has a double function of preventing the bottle as well as the cold coming out of the bag. Cooler Pad Champagne.
