Hi, if you put hot water in it there is no problem. Quencher models are designed to maintain both hot and cold beverages thanks to their double-walled vacuum insulated structure. You can comfortably use beverages such as hot tea and coffee — the product will keep them hot for hours. If you have any other question, we will be glad to help.

Hi, The Quencher H2.O FlowState Tumbler weighs about 370 grams. I can give this value as empty weight, of course it will be heavier when you put water in it. If you have any other question, we will be glad to help.

Hello, this model is mainly designed for cold drinks, and it is not recommended to put hot water. The inner coating structure of the product is not suitable for hot drinks. If you're looking for a hot beverage container, you can check out Stanley's thermos series. Happy to help if you have any other questions � �

Hi, great question. Even if the straw is plastic, it is completely safe to put hot water. Stanley designed this model for both hot and cold drinks; the straw is also made of temperature-resistant material. You can easily use hot tea and coffee. My only advice is that the straw will last longer if you want to wait for the very hot water to cool down a bit before pouring it in. But you won't have any problems with use. � �
