Why pay ballpark prices for your favorite beverage when you can bring your own anywhere? The BeerBelly makes it possible. It consists of a neoprene sling and a bladder that holds 80 oz., more than a six-pack of your favorite cold one. When worn under your clothes, it looks like you've put on a few pounds, effectively disguising your intentions. The BeerBelly works with either hot or cold beverages and includes a wide mouth for easy cleaning.
