When the weather gets cold and dreary, one of the simplest pleasures in life is warming up your bones with a hot beverage. But piping hot coffee won’t stay that way for long when you’re out in the great outdoors battling with your brolly as the rain pours. Thankfully, the Ember Travel Mug (£159.95) is here to the save the day. Using its accompanying app, you can set the temperature of the mug and maintain it so your drink will stay at the right temperature until you’ve drank the last sip. The app will also notify you when it’s at the right temperature so you can nurse your drink safe in the knowledge that you won’t burn your tongue. Equipped with a 360° leak-proof lid and a charging coaster, the mug can keep your drinks at the right temperature for up to 2 hours while you're out and about.
