Have you ever brought a 30 pack to a party and an hour later it was gone? The Beer Belly personal beverage system allows you to keep whatever beverage you choose to drink with you wherever you go. With its 80 ounce capacity and capability of comfortably fitting anybody up to 6'8" and 40" waist, the Beer Belly is ideal for hot or cold beverages. Its wide mouth opening allows you to fit ice cubes and makes cleaning a snap. The sling is made from comfortable neonprene and nylon material that is very durable. The bladder (similar to the common CamelBack bladders) is made of durable and insulating polyurethene. When put on under your clothes it makes you look like a man with a beer belly or a pregnant woman. The perfect disguise!
