I recently purchased these breast milk storage bags and have been thoroughly impressed with their quality and functionality. The bags are incredibly sturdy, with double-sealed seams and a reliable double zipper that ensures no leaks during storage or thawing.

Got a freezer full of these things and they do pretty well. I don't think their estimate lines are any worse than any other brand - there will always be some little bit off when it's a bag. The double zip really keeps liquid locked in. I have set these beside me on the bed after filling them and they don't leak when closed tightly. But do make sure they are closed even if you stand them up because they can easily tip over and spill! I've also had one or two that got scraped by the freezer closing and didn't realize it and the bag leaked when it was thawed. That was a pain, but something that I think could happen with any freezer bag.

These are my go-to breastmilk bags. They seal tightly, freeze flat for easy storage, and are clearly marked for measurements. For the price, you get a lot of value—especially helpful for pumping moms looking to build a stash.

These are good bags, but I’ve noticed a few would leak once I thawed them. I do love how easy they zip together and have double the durability. They also store nicely, I lay mine so they are flat. They are easy to open but still lock the goods in safely. The plastic is kinda thin, which is why I think they leak (they leak in the corners of the bottom) overall, they are good bags and do the job, with the exception of a few that leak.

hese pre-sterilized, BPA-free bags feature a double zipper seal and reinforced side seams to prevent leaks. The flat-freeze design maximizes freezer space and enables rapid, even thawing to preserve nutrients. A built-in pour spout and clear ounce markings simplify transfers and tracking.
