your breasts don't have air-vents,
why should baby bottles?

BARE™ is the only air-free baby bottle that closely mimics a mother’s breast and breastfeeding. With Air-plug™ technology that works similar to a syringe, BARE™ dispenses air-free contents to your baby, which helps to reduce gas/colic. The Perfe-latch™ nipple extends upon suction to emulate the mechanics of breastfeeding and reduce nipple confusion.
