Bodum Galileo 12 oz.
The insulating properties of a layer of air are well established. After all, that's how a thermos bottle works. But no one has ever created all-glass drinkware that insulates with double-walled construction — until Danish design maestro Jorgen Bodum, who pioneered the use of ultra-clear, ultra-light, borosilicate glass. Encircling air chambers keep hot drinks hot for hours, without searing your fingers. And cold beverages stay icy cold — without annoying condensation that can destroy the finish on fine wood tables. Choose sets in nouveau Bordeaux, classic Athena, stackable Galileo, or Coffee Mugs.
