The Thin Red Line Can Koozie offers a solution to your canned beverages that get warm too fast while fully exposed to the warm air or by stealing warmth from your hands. Now, you can get rid of both of those problems while showing support for the brave men and women in Red. The Thin Red Line American Flag is proudly printed onto the Koozie, also referred to as a hugger or huggie by some. Don’t let your beer get warm. Don’t let your hands get cold.
