This hardworking thermos bottle Flask, handsomely styled in signature Harris Tweed, is a celebrated addition to the flasks we already love! The best vacuum flasks perform a dual role: they keep hot liquid warm for your nordic ski adventures and days playing pond hockey, and they keep cold drinks cool, for those hikes to your favorite swimming holes in the height of summer. The Harris Tweed sleeve with bespoke stag lining is removable for hand washing.
How do Thermos flasks work? In short, they use a double walled construction, with the air removed from between these walls, forming a vacuum. Heat struggles to pass through the vacuum, meaning liquid stays at a roughly constant temperature.
