What it does

A 50 pack of pre-sterilized, self-standing 6 oz (180 ml) bags with a double zipper for storing breast milk in the fridge or freezer.

Stands on its own for filling and can be laid flat to freeze
Write-on area for the date and time milk was expressed
Measurement markings on the bag
Philips lists it as compatible with its Comfort electric and manual pumps

A low cost bag for parents storing modest amounts of milk who want a double zipper and a bag that stands up to fill. The trade-offs are small: some find the opening tight to fill and the tear tabs fussy, and Stork Mama suggests them more for short term storage than a large freezer stash.

How it compares

Lansinoh Breastmilk Storage BagsBetter for a large freezer stash; both Stork Mama and Mom Loves Best rank them first$

Kiinde Twist PouchesBetter if leak proofing matters most, with a screw cap instead of a zipper$$

Medela Pump and Save Breast Milk BagsBetter for Medela pump users who want to pump straight into the bag$$
