Breastbags are pre-sterilized and have a patented double zipper seal to prevent leakage. Designed with busy breastfeeding mothers in mind, they can lay flat for space-efficient breast milk freezer packing or stand upright for convenient refrigerator storage. They feature a convenient pour spout at the top for easy breastmilk transfers to baby bottles with fewer spills. Pump directly into storage bags for convenience and reduced waste.
