The slider is what earned this mug the top spot. A flat cover rides across the sip hole and seats over it, so a full 12-ounce mug can lie on its side in a tote without painting the inside of your bag with coffee, and that is more than most of the lids here manage. The insulation is honest too: the outside stays comfortable with a fresh pour inside, and the rating is six hours hot and up to 24 cold.
Drinking from it is the quieter pleasure. The spout is an oval opening with a rounded lip rather than a bare threaded hole, so sips are clean and coffee does not pool in the lid where you have to taste it again later. At 5.92 ounces empty it adds almost nothing to a bag, and the round body is easy to hold one-handed at a keyboard.
Two things to know before ordering. The cup is hand wash only, though the lid can go in the dishwasher, and thin stainless picks up dents when it meets a parking lot. Neither has changed our recommendation for someone who wants one mug that goes everywhere, and the limited lifetime warranty covers the construction. If you drink at a desk and would rather have a handle and a dishwasher-safe body, the YETI Rambler is the better answer.

Worth Noting

- Finish dents on a drop
Our pick for coffee that leaves the kitchen: the slider seals over the sip hole, so 12 ounces can ride in a bag and still be hot at your desk.
