To obtain the correct suction during pumping sessions; the Spectra Single Breast Shield centers over the nipple to create a seal around the areola. It creates a vacuum to gently draw the nipple into the funnel to extract milk. As the breast shield is manufactured without PBA, it is easy to clean and safe for moms and babies.
