I love my coffee to stay hot and every cup I have always loses the heat after some time elapses. I wanted to try the Coldest as I am a HUGE fan of these products for my icy needs and am so glad I did! I wish there were more color options when I bought my newest Coldest edition but the yellow isn't too bad and it's the product that counts and I am beyond pleased again with my Coldest cup! HIGHLY RECOMMEND !!! ( you can see i also have my 32oz with it!)

These tumblers keep my coffee hot for hours, even with the plastic lid! They’re redesigning them in 2025, and I cannot wait to purchase another upgraded version!!

Another excellent Coldest cup. I won’t buy any other brand , Coldest is the only brand you need. The colour is absolutely superb and definitely keeps your tea/coffee hot and water cold. Go on treat yourself to the best cups and bottles you will buy.

I'm in love with these tumblers. I bought 2 and use them daily. If you keep the top on they'll stay hot for hours. I like to leave the top off till it gets to the perfect temperature and then close it.

I hate when my tea goes cold too fast. This seems to stay hot longer. I can make this in the morning and still hot when I get to work. Haven’t tried with Starbucks next. I always order extra hot there. It’s pretty but wished I’d ordered the purple.
