Do the bottles keep milk warm?
The current bottles are not designed to insulate their contents. As with glass or plastic bottles, when you put warm or cool liquids in a stainless steel bottle the temperature of the liquids will slowly change to match the temperature of the room.
We do plan to introduce insulating double-wall vacuum bottles which will keep liquids warm or cool for up to six hours. If you would like to be informed of new introductions please e-mail info@PuraStainless.com and we will notify you when insulated bottles are available.
