Most coffee drinkers would agree that a good cup of coffee can- and should- be had at any time, but they will likely also say that hot or cold coffee has a short perfect temperature life’. Hot coffee must be hot, and ice coffee must be cold. To give our dedicated coffee lovers a cup suited to their needs, we created the Declan coffee mug to best hold the coffee’s ideal temperature. Following our Declan design, the coffee mug in this series has a double wall application to maintain your dink's hot temperature while protecting your hands from the heat.
