Dr. Brown’s Natural Flow Storage/Travel Caps for Wide-Neck Bottles, 2 Pack

These lids are a must-have for any Dr. Brown’s bottle user! They fit perfectly, create a leak-proof seal, and make storing breast milk or formula so much easier. I love using them for travel, as they prevent spills in the diaper bag. Super easy to clean and durable—highly recommend for busy parents!

I originally got these caps for warming milk but grew to love their versatility in regards to storing and traveling with milk. They don’t break and are easy to clean. No leaks and no issues.

Fit perfect. Helps to store my milk without the other pieces ! Functions amazing!

These caps are great for traveling with, and storing bottles in fridge. We were using the discs inside the bottle nipples for daycare and traveling with milk but they were constantly leaking. So we switched to these and they made all the difference. Highly recommend these if you are pumping or formula feeding your kiddo!!

These caps are great! I use them to mix the formula instead of having the nipple on the bottle. Makes it easier to mix! Worth every penny!!

So glad Dr. Brown's sells caps separately. I pump into the narrow neck and needed these for more storage. For a while I was using some extra Medela caps but I couldn't stand the leaks! These fit much better. No more leaks, easy to clean, and make travel so much easier. Nice thick plastic, these seem like they will hold up well.

These are perfect for storing. I use these to store in the fridge and when I put the milk in my bags. It keeps them from leaking. I would totally buy these again.You also use these if you get the sterilizer. But it comes with them, so if thats the only reason you need them, don't bother.

I have lots of Quattro Stagioni bottles and have been struggling with their lousy bottle caps. For the regular jars, I have lots options, including for canning, because they are a standard size. But not the bottles. I can't use these caps for canning, of course, but for regular storage, they are great! It's wonderful to have an option finally!The only caveat is that there's enough inconsistency in the bottles that the caps don't actually fit on all of them. So far, it's about 1 in 10 for the "pint" size jars, 2 in 10 for the "8oz" jars, and out of 6 "quart" jars, one of them doesn't fit. But it's the jars that are the problem, not the caps.I use the jars to "can" (frozen) fresh lemon juice from my tree and fermented red pepper sauce (sriracha -- in the refrigerator). Neither of those processes requires heat canning, so I don't need caps that can withstand a canner. However, I do like to can tomato juice and it would be nice to have a canning lid for the bottles -- the ones QS makes are very unreliable for canning.
