The Nespresso Nomad Travel Mug is a tall, large, double-walled stainless steel travel mug with a push-to-open button. It has a 360° opening so you can drink from any angle or position on the lid. Reviews note that it keeps coffee hot for up to 5 hours and water cold for up to 11 hours, and that it stays hot forever and doesn't leak. However, some say it's not the easiest to carry around and feels a little big in the hand
