When we travel to warmer climates, a TUDI wrap is a necessity. If we do not wrap our glasses of cold beverages, they sweat profusely and water runs down the table. We purchased the large ones to go around taller glasses, and the new tall cans. With the cans being made in such different shapes, the old fashioned Koozies were not cutting it. The TUDI WRAPS are great - custom fit to whatever size of beverage you are drinking. And they compact nicley to fit in your pocket or purse. Great product. We bought some to give to our friends in Mexico.
