Can coolers are insulated sleeves made of foam or neoprene that typically keep a 12-oz. beer cold. Can coolers, often called “koozies," "coolie cups" or even "huggies," can be used to insulate any can or bottled beverage! They also keep hands dry and can easily fit into a pocket when not used. Promotional can coolers are often used as guest favors or giveaway items. Choose unique insulators like our slim can coolers, zipper bottle insulators or classic thick foam coolie cups to really stand out.
