Stainless Steel Insulated Thermos Flask

Coffee still hot at the summit, water still cold at the end of a July walk. 316L steel liner, push-button lid. Just as handy for hot tea on frosty autumn dog walks across the UK.

An unbreakable thermos flask for every British season

Built from 316L stainless steel with no glass liner, this unbreakable thermos flask survives the knocks a normal vacuum flask can't — dropped on a campsite path, thrown in a rucksack, or jostled in the car boot. The vacuum wall keeps drinks hot for 24 hours and cold just as long, with a push-button lid that doubles as a cup. Available in six sizes and four colours, from a daily commute flask to a large-capacity bottle for a full day on the trail.
