These hats are made from real beer boxes and are officially licensed. They are made in the USA and made with quality. Think of how strong those boxes have to be to support the weight of 30 beers! Now add the stitched reinforcement that goes around the edge of the hat, with a wire ring inside. The cardboard used is called "wetboard" because it's coated with urethane or plastic (depending on the brand) so that the moisture that condenses onto the cans does not ruin the cardboard. Be confident that your Beer Hat will be able to withstand a reasonable amount of abuse.The hats feature an elastic band around in the inside to make these hats One Size Fits All.
