Avent's unique AirFree vent is designed to draw air away from the nipple keeping it full of milk. Even when the bottle is horizontal, the nipple stays full, so your baby can drink in an upright position. Feeding in an upright position can help reduce reflux, and aid in digestion. Philips Avent Anti-colic bottles can be used with or without the AirFree vent

The shape of the nipple allows for a secure latch, and the ribbed texture helps prevent nipple collapse, for uninterrupted, comfortable feeding. You can feed comfortably, using Philips Avent bottles with or without the AirFree vent. The AirFree vent is compatible with all of our Philips Avent Anti-colic bottles.
