Engineered to keep your drink perfect from the first tailgate to the final whistle, the Michigan Wolverines 22oz. Stadium Tumbler from Indigo Falls is housed in durable 18/8 stainless steel. The double-walled, copper-coated vacuum seal locks in temperature while exterior graphics celebrate the iconic home stadium. Superior insulation keeps coffee hot for up to eight hours during a chilly morning kickoff or a beverage ice-cold through the fourth quarter.
