The double-seal zipper is what sold me—not a single leak after freezing flat and thawing in warm water. Pre-sterilized means I don’t have to boil anything before a night pump, and the 6 oz capacity fits my biggest sessions without waste.

I’ve used a lot of bags over the years and these are the first ones where I actually trust the seal enough to lay flat in the freezer without worrying. The 6 oz size is perfect for my pump sessions, and they’re already pre-sterilized so I just grab and go.

The double-seal zipper really does the job — I've tossed these in my work bag and tossed them in the freezer flat, not a single leak. They're pre-sterilized, so I just fill and go, which saves me a whole step on busy mornings.
