The MadDogg Heat Sleeve is a single use coffee sleeve that will keep your coffee at the optimal drinking temperature for up to 3 hours. With tested and proven results, the MadDogg Heat Sleeve will revolutionize the way coffee is consumed.
"I developed the idea for the Heat Sleeve as an avid coffee-drinker. After the repeating frustration of throwing away cold coffee, along with the constraints of a college budget, I began drawing up the idea in a journal. I first pitched it to my parents and sister while we were at a local coffee shop, they were immediately interested. Since then, they have seen every prototype-the good, the bad, and the ugly- and still believed in my idea. The idea came about after researching a technology to create a disposable device that works in conjunction with a disposable coffee cup to keep coffee at a drinkable temperature longer. Through discussion with those with more subject matter expertise and many days spent prototyping, the MadDogg Heat Sleeve came to life."
