    • Great quality bags!
Size: 100 Count Style: 6oz
These bags are very durable and easy to use. I’ve never had any leaks, and they freeze flat, which saves a lot of space. Highly recommend for breastfeeding moms!

    • Better than Medela
Size: 50 Count Style: 6oz
After discovering that Madela bags can make your milk smell and taste rancid, I switched. But, I also did a little comparison work: Lansinoh bags can hold up to 6 ounces of breast milk. Medela bags can hold up to 5 ounces of breast milk. Lansinoh: On the simplest level, the Lansinoh bag is easier to open and pour milk into than the Medela bag. The reason I find it easier is because of the material the bag is made out of and the bag is more pliable. You open the bag by removing a small strip that is perforated on the top. There are two seals on these bags, which is a huge plus. It's a comfort in preventing leaks. The reason why Lansinoh wins the freezing process is because they lay flat very well. I've found that when laid flat, the bag freezes into a solid rectangle of milk that is consistent in thickness. It is also easy to "stack" once frozen which is very helpful for organizing. It's also important to squeeze all the air out of the bag which is much easier to do since there is not a large plastic section at the top, like in the Medela bags. Medela: The Medela bags have the ability to be attached directly to a pump. As a result, there is a large plastic area on the top of the bag that is perforated. This makes these bags a little bit more awkward to open. Lansinoh: Since these bags are fantastic for the freezing process, they are easier to thaw because they are consistently the same thickness. They look like a perfect rectangle of frozen milk. Or you can freeze the bag standing up. My husband loves how easy it is to thaw these out. Way easier than Medela. Medela: Bag leaks when you thaw it and sometimes they leak in the freezer (which really is a mess). This is because there is only one seal instead of the double seal on the Lansinoh bags. ... show more

    • Best breastmilk storage bags I’ve used
Size: 200 Count Style: 6oz
Review Image by Chantel Pike
The media could not be loaded. I’ve tried a few different breast milk storage bag brands, and in my experience, Lansinoh has been the best quality by far. They’re thick, durable and freeze really well. Across both of my sons, I’ve had only a few bags ever break — which is amazing compared to other brands I’ve tried. They freeze flat, which is great for storage capacity in the freezer and makes thawing much quicker. I also appreciate that they’re BPA-free and have the tear-away tops so you know the bag is completely sealed before and overall very easy to use. While I normally don’t pump directly into bags, these are designed for that option if you prefer — just keep in mind you may need an adapter if you’re not using a Lansinoh pump. I go through bags quickly, so I love that you can buy a 200-count box to cut down on constant reordering. The price is affordable too, especially for the quality. Highly recommend these for pumping mamas! ... show more

    • Durable and Thick, Easy to Use, 6 oz Max Capacity
Size: 100 Count Style: 6oz
Awesome storage bags! The plastic is thick and durable. Each bag is sealed and a little piece of plastic needs to be ripped off just prior to use. This keeps these bags clean and free from any contaminates. They fit 6 oz in each bag. The bag is clear and the fill lines are easy to see. The bottom opens up as you are filling to stand upright which is very helpful. It is easy to get the air out of the bag and the double ziploc makes it easy to seal shut. I have never experienced any leaking. The tab to write information is on the top of the bag, which is great if you forget to write on it prior to filling. There is a spot for date, time, and amount. These bags freeze flat and make it easy to defrost. I love these bags and will continue to purchase! ... show more

    • Much Better Than Medela Bags
Size: 100 Count Style: 6oz
I used the Medela bags when I first started pumping. So you know, I pumped for a year with my first child and have been pumping three months so far with my second so I have a lot of experience storing milk. Here are the issues I had with them: - Medela bags only hold 5 ounces and will not close properly if more is added; - Medela plastic is firmer which I didn't like; - Medela bags only have one seal and it's not dependable. The milk in some of the fuller bags (4-5 ounces) I put in the freezer expanded and the seal came apart and the milk spilled out!! I lost many bottles of milk using these bags; and, - Medela bags ounce measurement lines aren't accurate (at least from my experience. Why I love the Lanisoh bags: - Lanisoh holds 6 ounces or more of milk. It is riskier to put more milk in but I have put 7-8 ounces in many times and even frozen it and haven't had any issues. - Lanisoh is made of softer plastic which I love for two reasons. One, you can more easily get the air out of the bag and seal it. Two, when the milk chills the fat of the milk rises to the top and also tends to cling to the sides of the bag. What I do to mix the fat back in is take my finger nail on the OUTSIDE of the bag and gently scrape the fat into the rest of the milk The soft plastic makes this easy to do. - Lanisoh has two seals and they work! I have even held a full six ounce bag upside down for a couple seconds and it didn't leak at all. I have frozen 100+ of these bags and never lost any milk for any reason other than that it was too old : ) Only reason I gave these bags 4 instead of 5 stars is that I can't easily pump straight into the bag like you can with the Medela ones. However, I have taken the medela bag pump attachments and pushed the sides of the Lanisoh bags onto the attachments so they hung like the Medela bags. It does work but it is not as convienent and not a dependable way to pump. Instead, I usually pump into Medela bottles and pour the milk into the bags. Some reviewers have had issues with these bags which is unfortunate because I have used upwards of 200+ of these bags in the fridge, freezer, and travelling and have not had one singe issue. ... show more
