The Beer Belly, a hands-free hydration system, looks like a beer belly when worn under clothing. It consists of two parts: the sling and the bladder. The sling is designed to fit users up to six feet, eight inches tall, and up to a 40-inch waist. Made of neoprene and nylon, it insulates and feels like skin to the touch. A hook and loop is used for custom sizing. The bladder, made of polyurethane, holds up to 80 ounces of any hot or cold beverage and fits in a custom-shaped pouch in the sling. The bladder has a wide mouth opening for adding ice and to simplify cleaning. Clean the bladder with Beer Belly cleaner, sold separately. The sling can be washed by hand or on the gentle cycle of a washing machine, then hung to dry.
