What to Pack For a Cold but Cozy Ski Trip in Jackson Hole

Rovr ChillR 12-ounce Insulated Lowball Tumbler ($25)

During my stay, the temperature got as low as -21 degrees Fahrenheit — the coldest temperature I've ever encountered. I carried this Rovr tumbler with me everywhere and filled it with hot tea throughout the day to ensure I stayed warm. Pro-tip: I took this to après-ski at Mangy Moose and they filled it with hot water for me on the way out.
