I once used this koozie as I was hitchhiking through Death Valley in July of 2010. A Caribbean Yellow Toyota Tercel was hauling ass down the road, slowing down as it approached me. As it rolled past, the driver reached into a cooler and threw an ice cold 12 oz can of Three Weavers Seafarer Kölsch out the window to me while yelling, “I can’t give ya a lift, but I can give ya a beer!” Thank God I had this koozie in my back pocket, because without it, that beer would have been turned to hot barley tea in 10 seconds flat. Instead, I enjoyed the brew the way it should be – frosty, fresh and freezing. Thanks Koozie.
