This coozie functions just as you'd expect a coozie to function. It keeps your drink child, it fits bottles and cans, it minimizes cold fingers contact with beverage containers. What truly sets this masterpiece apart is it's beard, printed right on the side! Everything with a beard is inherently more attractive, more trustworthy, more capable in it's task. In other words, a beard makes things better. Which is why this is the best coozie in the world.
