Smash Glass Travel Mug

I bought this mug almost a month ago. It feels great. Good weight. Good silicone feel in the grip. But the problem is that when I am walking the coffee seeps out in between the lip of the glass and the silicone lid. It's almost as if the lid isn't snug enough. This results in the coffee dripping from the side of the mug down your hand and making a mess. If the lid does manage to keep the coffee in, the spout - or the little hole on top of the lid - acts as another outlet for liquid when you're on the move - but this may be common across all travel mugs like this.
