A good thermos has two main jobs: It should hold enough coffee to last the entire day, and it should keep that coffee hot throughout. We tested 27 different options, and although most of them kept our coffee warm, the Stanley Classic stood a cut above the rest. The thermos is large, easy to pour, comfortable to hold, and dishwasher safe. The only downside we encountered was its metal lid, which you may find to be a little cold on chilly mornings. We’ve seen better deals for this thermos in the past, but this is the first notable discount we’ve posted for it since 2020. If you’re looking for the best option to keep your coffee hot on the go, the Stanley Classic is worth a glance.
