ZERO.ZERO 270 ml anti-colic feeding bottle replacement pouch

The ZERO.ZERO bottle's anti-colic pouch works like mammary glands by retracting as baby sucks. This ingenious system requires no outside air to compensate for the vacuum inside, eliminating air bubbles and reducing air intake, which helps to reduce colic. What's more, it prevents air from oxidising the milk and destroying nutrients, especially those found in breast milk.
