The Constrictor Can Cooler is the jack of all trades. It is multifunctional and is a universal can cooler. With its extended velcro it has the ability to “constrict” to almost everything from a slim can to a plastic cup. Throw it in the freezer and the gel becomes frozen making it a can chiller and will make your drink even colder than when it came out of the refrigerator. The constrictor can also lay flat and be used as an “Ice Pack” for your cooler.
