This baby keeps a coffee hot for hours. My kids swim train and we leave for the pool at 3.30pm. I make 2 coffees. The second cup is still piping hot at 7pm on our drive back home.
I bought my husband one too. He takes it diving with him. He’ll leave it on the beach about 9am, and when he finishes his dives about 3pm, again it’s still a nice hot coffee. He said it’s the best travel cup he’s over had too 😊
