The double-walled Ecooe glasses
made of tasteless-borosilicate glass that are light and robust at the same time. Under the glass floor is a hydrophobic silicone membrane, which serves to equalize the pressure between the glass walls. It leaves the glass 'breathe': with cold drinks, no condensation forms on the glass surface and the glass does not leave any unsightly water rims. These glasses are also ideal for serving ice-cream and other desserts.
