Cold use bottle can holdwater. However, you tend to scald when you use cold use bottle with straight upmouth to drink hot water. When you cold use bottle, we sugest holding lowertemperature water.
The heat retention effectis changing along with the environment. Heat insulation Rating is based onwater at a starting temperature of 203°F (95°C) at a room temperature of 77°F (25°C).Cold insulating Rating is based on water at a starting temperature of 40°F (4°C)at a room temperature of 77°F (25°C).
