Our 25oz vacuum-insulated bottles keep liquids hot or cold all day. This compact size fits easily in your backpack and holds enough to keep you hydrated at the dog park or while out running errands. Or fill it up in the morning with enough coffee to fuel you through your commute and most (or even all!) of your work day.
Double wall vacuum insulated products keep beverages cold or hot for hours. Cold stays in and does not transfer to the outside surface or what is known as sweating. Heat stays in and does not transfer to the outside surface thus you will not burn your hand.
