Well-insulated, no leaks, easy to drink from—this mug is a winter traveler’s dream. The push-button lid makes for, yes, one-handed operation: On a snowshoe to Fern Lake in Rocky Mountain National Park, one Colorado tester sipped hot tea without taking off her gloves or putting down her trekking poles, thanks to the wide, easily depressed button. While ice climbing at Lincoln Falls, another Colorado tester trusted the seal (the button is hard to press accidentally) enough to toss the full mug in her bag without fear of spilling coffee, cream, and sugar all over the rope. “It’s the perfect size for a couple to share coffee,” she adds.
In our freezer test, after 8.5 hours in an 8°F environment, our coffee was still a palatable 88°F (down from its starting temperature of 185°F)—and that’s without prewarming the mug. Extra nice: The dishwasher-safe lid disassembles for easy cleaning, so you can go ahead and bring the sticky hot chocolate. Keep track of all the small parts, though—during washing, one tester lost a key gasket that compromised the seal. $35; 13.9 oz.; stanley-pmi.com
