Double-walled insulated glassware — keeps drinks cold without condensation
Double-walled borosilicate glass with an air insulation layer that keeps cold drinks cold and hot drinks hot — without sweating on the outside. No ice required. No rings on your table. Just your drink, at the right temperature, in a glass that looks as good as it performs.
How the double-walled glass works
Two layers of high-quality borosilicate glass are sealed with a vacuum air gap between them. This insulation layer stops heat transferring between your drink and the outside air — keeping cold drinks cold for longer and preventing the condensation that leaves rings on surfaces. The same principle as a thermos flask, in an elegant drinking glass.

Why it makes an excellent gift
The double-walled glass is one of those gifts that makes immediate sense the moment you hold it — noticeably lighter than it looks, perfectly balanced, and with a satisfying quality that is hard to fake. It is the kind of thing people would not buy for themselves, which makes it exactly the right gift.
- No condensation — no ruined surfaces or wet hands
- Keeps drinks at temperature for significantly longer than standard glassware
- Borosilicate glass — tougher and more heat-resistant than regular glass
- Dishwasher safe
- Gift-ready presentation
Frequently asked questions
Why does double-walled glass not sweat?
The air gap between the two glass walls acts as insulation, stopping the cold temperature of your drink from reaching the outer wall. Because the outer wall stays near room temperature, condensation does not form.
Can you use a double-walled glass for hot drinks?
Yes. The same insulation that keeps cold drinks cold also keeps hot drinks hot — and protects your hands from the heat of the liquid inside.
Is it dishwasher safe?
Yes, both sizes are dishwasher safe. Hand washing will extend the life of the glass.
