A hot drink can be the saving of many a picnic, walk or day out. There’s nothing quite as reviving as a much-needed cup of soup or hit of caffeine. Few things beat sitting back in one of the best camping chairs and taking in a beautiful view while enjoying a warming drink when you’re pitched up at your site, too. However, you’ll want to make sure you have one of the best flasks for hot drinks to make sure your beverage stays at the right temperature.
For many, Thermos is the go-to brand – indeed it has become a byword for a hot flask in the way that Hoover has for vacuum cleaners (and take a look at our best motorhome vacuum cleaner guide if you’re after one).
However, there’s a wide range of flasks, bottles and cups available, which employ different technologies to keep your drinks at the perfect temperature. Many of them are equally suited for use as water bottles and we’ve chosen a range of products that illustrate just how many flasks for hot drinks there are.
Whichever flask you go for, always remember to sip your drink, sigh contentedly and say: “That hits the spot!”
