Finding a perfect coffee mug can be a challenge, but not when you have this mug! The Mighty Mug’s superior quality is a result of double wall construction, which not only helps keep your hands dry, but it helps keep your drink at the temperature you want it. It keeps hot drinks hot for 4+ hours, and keeps cold drinks cold for 14+ hours. But what really sets this mug apart is the magical ‘Smartgrip’ technology. It sticks to any flat surface, so it won’t tip over if it gets bumped, yet you can easily pick it up to drink out of. The Mighty Mug is perfect in size – small enough to fit into most coffee makers and cup holders, yet at 12 oz. it’s still large enough to deliver your caffeine fix!
