The Urban Thermos 500ml is a thermos bottle of double-walled stainless steel with a stainless steel cap. Water and drinks from a Retulp thermos taste better because there is no transfer of taste between the drink and the material.
An insulating bottle is an ideal upgrade for those who never go out without their bottle again. Now you can also keep your water and other drinks nice and fresh or warm. Ideal for the winter and an asset to your (flex) workplace so that you can hydrate yourself.
