The glasses keep hot drinks hot and cold drinks cold for longer. They don’t create any condensation water on the outside of the glass and are cool to the touch.

Capacity: 0.3l / 10 fl.oz
Materials: Borosilicate Glass, Silicone
 
* Dishwasher Safe – the vent is only permeable to air, not water.

An added hydrophobic silicone vent at the bottom of each glass constantly equalizes the air pressure between the two glass layers with the outside air pressure, either for hot or cold liquids. This significantly increases product stability.
