This tumbler truly is leak-proof.

Reduce Hot1 18 oz Stainless Steel Insulated Tumbler with Adjustable Flow Lid – Black. I got the tumbler with a handle. Perfect for everything cold or hot. Stays cold/hot for hours. Great materials. Surprised by the good quality and design. Lightweight yet sturdy, it features a non-slip bottom that I really like, making it almost like a coaster. The lid has a sliding option for how much/fast you want the drink to flow, and also a flip-top part with a silicone tip to seal the opening you drink through, and a silicone ring to seal around the perimeter of the whole lid. You could use a straw with this one if you prefer. Or a long coffee spoon/stirrer. I hate to say it, but I have knocked that thing over several times when in a hurry, and it never leaked a drop. So surprised! Yes, I recommend this tumbler and the brand itself. They have several great products. I'm getting some other styles as well.
