While Zojirushi is probably best known for their rice cookers and water boilers, they have quietly been making some of the best insulated mugs and water bottles for years. I've had the previous generation since 2017 (still working well!) and recently got their newer model. The best part about these mugs is the locking top so you don't have to worry about any spills, no matter where you shove this thing in your bag. I also love that it's fairly slim so I have no issues putting it in any backpack side pocket.
