There is a hidden silicone base to this mug that makes it difficult to tip over if knocked by accident. If you hit it sideways it will not move, however, when you lift it straight up by the handle the suction is broken and it lifts easily. The inside is stainless steel with double walled insulation. It comes with a lid that fits with a silicone seal which further reduces the risk of spills.
