These are awesome!! I have not experienced any leaking! They freeze flat and store easily!

They don’t leak. The oz on the bag are pretty accurate. I don’t really have any cons

I like these bags a lot! But I did have quite a few of them to leak once I started to thaw my milk

I like that Lansinoh comes with a lot of bags. Easy to use. Easy to store. Holds a lot of milk.

Great for storing milk. Easy to use, they don’t tear or break also didn’t have any leakage

I love these they make storage very simple!! I definitely recommend trying these out if you pump

No complaints! I like the double zipper. These are thick and don’t leak. Two thumbs up

I've never had any problems with leaking milk bags with this brand. They freeze and thaw out great.

I think the lansinoh breastmilk storage bags are the best of the best. They have triple the zipper.

Easy to use, label & stack. I've used them with all 3 of my babies and would recommend.
