The clear winner in this contest was the least “cool” cozy, a quintessential foam can holder imprinted with a questionably humorous saying, purchased at a truck stop for 99 cents. Despite its lack of charm, it was the most effective insulator, keeping the beer 59.1F (15.1C) after an hour.

Bravo, because I always just buy the cheap cozy's because I always lose them.
