It's only mid-May, and it's already hotter than blazes in Atlanta. But it's grilling season, so I head out to the patio, mop my brow and complain about the humidity. Fortunately, I can keep an ice cold beverage with me at all times thanks to my double-walled Serafino glasses which keep liquids at the ideal temperature whether hot or cold.
These cups are made of durable borosilicate glass, which is unaffected by heat and shatter resistant -- perfect when you have a handsy toddler around! I doubt it could withstand her throwing it on the ground, but at least a nudge shouldn't do these in. The Serafino glasses are microwave and freezer safe and come with a one year warranty to boot.
The double wall design keeps your beverage within the inner wall, so you don't get sweaty drinks that leave rings on your tables. I can't even think of drinking a hot beverage right now, but if that's your thing, this glass will be cool to the grip even when filled with hot coffee. These are fairly large sized glasses, and while their curvey. double-walled shape is attractive, I wouldn't bust these out at a dinner party. They're more of an everyday casual dining option.
When I poured myself a cold glass of water with no ice, just the way I like it, I was impressed to find that my water was pleasantly cool even an hour later despite the high temperatures outside. As of today they sell on Amazon for $34.95 for a set of 4.
