Aquaphile 17oz Coffee Mug to Go Stainless Steel Thermos Double Wall Insulated Coffee Cup Reusable Travel Mug with Leak Proof Lid, Navy Blue

I like this mug for so many reasons and I use it almost daily! First off, the lid goes on securely and the cover over the spout closes tightly. I have never had any problems with leaks. Second,it keeps my drinks hot for a long time. Third, it's easy to clean. Fourth- it's durable. I am planning on buying a second one for cold drinks.

Works very well and isn't too big to handle! It's just the right size to get enough soda from a can fits well or for some milk with your cookies it's perfectly sized!
