These Born Free wide neck glass bottles feature an innovative air vent that helps minimize colic symptoms. Each bottle comes with a level 1 nipple and a cover. These smooth glass bottles are easy to clean between uses, so your baby gets clean, safe milk during his next feeding. The clear basin lets you see precisely how much milk is left before heading out the door, reducing the risk of running out prematurely. Since the nipples only release liquid when the baby sucks, there are no accidental spills or leaks during travel.
