Insulation and seal

The core of this thermos flask is its double-walled stainless steel construction, which insulates the contents from the ambient temperature. This design keeps drinks cold for up to 36 hours and hot for up to 18 hours, without any condensation forming on the outside or making the bottle too hot to hold. The screw cap is 100% leakproof and hermetically sealed, preventing any spills.
