It’s honestly a small luxury watching my tea stay steaming hot through the glass while the outside stays perfectly cool to hold. The double wall makes all the difference, and the slim silhouette feels great in hand.

I keep reaching for this mug several times a day now. The double wall keeps my tea hot for a solid hour, and I can hold it comfortably with both hands the whole time, which is a game changer for cold mornings.

Finally a mug that doesn't scorch my fingers—the double wall really works, and my tea stays steaming for a good twenty minutes. It's become my daily desk companion, and the glass looks so sleek I don't mind it sitting out.
