Zero - Bottle
The zero water bottle has a capacity of more than 600ml, has a high autonomy due to its ability to keep the temperature. Inside the upper eco-leather coverings, find a freezer gel bag which will tend to always cool the contents from top to bottom. In the lower part, there are some resistors which by connecting a micro cable usb, heat the drink from the bottom towards up. The elliptical shape allows a greater stability.
