Had an the opportunity to take the bag out to track practice for my kids. We packed it with water and Gatorade! During a break my teenagers came over to grab something to &#x27;cool off&#x27; with... and little did they know they were in for a brain freeze! The IceMule had been sitting in the hot Kansas sun on the bleachers for over two hours. But everything inside was as cold (if not colder) than pulling things out of a refrigerator! None of the ice had melted and the drinks were COLD! Needless to say our family is sold on ICEMULE!
