Take control of those delicious but tricky-to-transport lunchtime favourites, with this insulated food flask by BUILT. It boasts a smart design, with a powerful double wall of vacuum insulation. This keeps hot food warm for up to six hours, chilled food cool for up to 24 hours and frozen food stored for up to four hours. Function meets style with this attractive large water bottle. Produced from top-quality, highly durable materials, these versatile flasks are more than up to the challenge of keeping pace with the busy commuter, frequent gym-goer, or the dedicated hiker. Double-walled vacuum insulation preserves drinks, without affecting the outer temperature. Fill this drinks bottle with a generous cupful of hot tea, coffee or soup, and it will stay warm for up to 6 hours without burning your fingers. Iced tea, water, and other cold drinks remain refreshingly cool in this handy thermal bottle, too.
