Ever started your day at work with a hot coffee and then needed a cold beer by the time the day was done? Have we got something for you! Our Black Duplex Tumbler serves as a 22 oz travel coffee mug with a stand that turns into an insulated cooler for your standard 12 oz beer can. Both compartments are vacuum insulated, double walled stainless steel so your coffee will stay hot while your beer stays cold. Get our dual-purpose Duplex for a well-rounded day!
