Whether it's a scalding coffee that needs to survive a cold summit, or an ice-cold cocktail that has to last an afternoon in direct sun, a good flask should still be doing its job hours after you filled it. That's the real difference between an insulated flask and an ordinary bottle: proper vacuum insulation keeps hot drinks hot and cold drinks cold for far longer than you'd think. If you're brewing on the move, pair your flask with a stove from our stoves range and kit from coffeeware to keep the coffee coming wherever the day takes you. And for the times a flask isn't quite what you need, our water bottles cover everything else.
