Yes, you can put cold milk into Hydro Flask insulated water bottles. However, you should not put hot milk into the Hydro Flask insulated water bottle and hold hot milk for long time.
There are two reasons why you can’t use Hydro Flask insulated water bottles to hold hot milk for long time:
Hot milk will deteriorate if placed in the thermos for a long time, which will make people sick.
Keeping hot milk in an insulated for 3-4 hours will spoil the milk. In addition, the constant hot temperature in the thermos can destroy the vitamins in the milk and directly affect people’s health. People who drink this kind of milk are prone to diarrhea and indigestion. Moreover, using an insulated water bottle to store hot milk will cause the water bottle to produce peculiar smell, which is not easy to remove, which is not good for prolonging the service life of the Hydro Flask insulated water bottle.
Hydro Flask insulated water bottle has the function of heat preservation, so many people often use Hydro Flask insulated water bottles to store hot milk, tea, soy milk and other foods or beverages. Especially in winter, more and more people use insulated stainless steel drinking bottles to store these foods.

The material of Hydro Flask the stainless steel insulated water bottle is made of 18/8 stainless steel. The stainless steel material is stable, and the food and beverage will not change in a short time. But do not place acidic and alkaline foods for a long time. Although the stainless steel vacuum flask is more resistant to corrosion than other materials, it is still a metal texture and will undergo chemical changes for a long time.
Ninety-nine percent of the stainless steel material is elemental iron. Milk contains carbonic acid after fermentation. It reacts with elemental iron and corrodes metals. It will dissolve a large amount of harmful carcinogens nickel or chromium. Dairy products, tea, coffee, etc.
