Low Spill Risk Coffee Tumbler?

Hi, was wondering if anyone has any recommendations for coffee tumblers. I had a tumbler that broke a while ago and haven’t gotten around to replacing it. It wasn’t perfect and I still spilled because I’d fall asleep before closing it but it was safer than a mug. I’ve been on a good streak of not falling asleep and spilling coffee on myself but I don’t wanna get too comfortable. Thanks!
