Weighs only 130 g. This is our brand new User Experience innovation. Unlike most water bottle belts on the market, which rely on custom water bottles that cost a fortune and not sanitary due to the fact that it requires washing and cleaning. We've come up with the perfect solution! A water bottle belt that hoists bottled water you can buy from any store. And we take out innovation one step further with thermal materials to keep your drinks cold or warm for double the duration. It is designed deliberately with TWO belts instead of one, to make sure that the bottles stay securely on your body and that they are worn with comfort by conforming to the contours of your body.
