Internal Vent System

1. Air enters the bottle collar and routes directly through the internal vent system.
2. The air channels through the vent tube, bypassing the milk, to the end of the bottle.
3. The vent prevents aeration of the milk, vacuum pressure and nipple collapse.
4. Baby feeds comfortably while milk flows freely, like breastfeeding.

The Dr. Brown's  vent system reduces air bubble oxidation to help preserve bottle milk nutrients.
