4.8 star reviews

Parents Rate Mason Bottle 4.8/5

Parents give us an average review rating of 4.8 on MasonBottle.com. We like to say that parents buy our bottle for the health benefits it provides to the baby, but stick with the bottle because it’s so easy for them to clean and so convenient to use.

"My baby is mostly breastfed, but can pretty easily adjust to this nipple thanks to its shape. We went up to the medium flow right about 3 months, so I've found the design to be well matched to age too". 

-Jenny, Mason Bottle Customer


"As an exclusively breastfeeding mama, I was nervous about finding a nipple my son would like when I went back to work. I'm happy to say that the shape of this nipple is perfect for breastfed babies and fits perfectly in my mason jar lids."

-Sebrina, Mason Bottle Customer

"I purchased the Mason Bottle kit because I was looking for an eco friendly/sustainable product, that was affordable! I like that it is reusable and non toxic. The sleeve is perfect for clumsy moms like me and it comes with a lid for when on the go. Also it is super cute! I would definitely invest in mason bottle products because they grow with your child and you can find many uses for the jars afterwards."

-Stephanie, Mason Bottle Customer

"These are my favorite products to tell other moms! Being able to repurpose the jars after the feeding stage sold me originally. Now I see so many other benefits that come along. No plastic bottles! Easy to clean! Store breast milk in jars then into the freezer, then directly to warmer for less milk waste! Give these a try!!"

Mason Bottle Benefits

Breast-Like Shape and Flow

The wide design helps ensure a breast-like latch.  Our nipples are designed to flow smoothly to mimic the pace of breastfeeding. 

Healthy Materials

All of our Mason Bottle products are produced using the highest quality and safest materials in order to provide our customers with durable, healthy, and safe bottles and accessories. Our products are free of BPA, BPS, phthalates and other toxins and chemicals. 

Worried About Glass Breaking?

We also make a silicone bottle (that's still mason jar compatible), so you can still avoid plastic, but also feel comfortable using Mason Bottle with older babies and on the go.

No Spilt Milk. No Waste.

Mason Bottle makes pumping and bottle feeding easy as can be. Milk can be stored and then warmed in jars, meaning no single-use breastmilk storage bags, and no split milk going from bag to bottle.

Leak Proof and Anti-Colic

Just because our bottles are made with mason jars, doesn't mean our design is old fashioned. The high-performing design is both leak-proof and anti-colic with our FussFree (TM) ventilation system built right into the nipple.

Easy to Clean

Glass doesn't hold onto milk fats like plastic does so our bottles won't get yellow, cloudy, smelly, etc. No sanitizer system required. Since there are no hard to reach places on the nipples or bottles, bottle brushes aren't needed either. Just a bowl of soapy warm water or a dishwasher.

Reuse for Years to Come

The jars can be used again and again for breast milk storage, baby food portions, and sleeves can be used for toddler training cups, keep your coffee hot, and more.

DIY Option

The Mason Bottle DIY Kit includes everything you need to create two baby bottles using mason jars you already have at home.

Did You Know: "The American Academy of Pediatrics recommends avoiding plastic whenever possible for the bottle stage and beyond."

Slow Flow Nipples to Support Breastfeeding

Slow Flow Nipples to Support Breastfeeding


Pediatricians and Lactation Consultants recommend using the slowest flowing nipple a baby will accept because slow flow nipples simulate the pace of breastfeeding. For this reason, all of our glass bottles come with Slow Flow Nipples for 0-3 months.


Breastfed babies can even continue to use Slow Flow well beyond 3m, moving up to Medium Flow only if/when the child shows cues of impatience with the pace of feeding as they get older. 


The Only Bottle with a 100% No-Risk Money Back Guarantee


We’ve checked the return policies of all the major baby bottle brands, and as far as we can tell, Mason Bottle is the only brand with a money-back guarantee.


All other bottle brands only accept returns on unused and unopened products. But how can you know if a bottle really works for your family without trying one first?! You can’t. So we decided to create a new policy that puts families and quality first. 

A Bottle For Every Budget

Here at Mason Bottle, we believe that healthy doesn't have to be high-end. We have designed our bottles to not only be eco-friendly, health friendly, but budget friendly as well. Whether you want to try, DIY, or buy a gift set, we have an option for you:

  • Will My Baby Accept the Nipple?

    All babies are different, so it's not humanly possible to design a nipple that 100% of babies like. This may mean you need to try a couple different bottles for your child.  At Mason Bottle, our return rate is 3%, so there’s just about a 97% chance you and your baby are going to love this product. But just in case you fall into that 3%…we also offer a money-back guarantee.

  • What Kind of Jars Can I Use?

    Our products are designed to use any regular mouth mason jar. This means, the brand isn't important and neither in the size. However, our silicone sleeve is designed to only fit either a 4oz jar or an 8oz jar. 

  • Why Mason Jars?

    At Mason Bottle, we believe healthy doesn't have to be high end. Since glass baby bottles can be expensive, we knew making a bottle compatible with mason jars would help families save money, especially if they already have jars at home. Mason jars are also a cleaner and more cost-effective alternative to breast milk storage bags. Simply store breast milk in a mason jar, then add the Mason Bottle nipple to turn it into a bottle.

The Mason Bottle Story: Put Health First, Do More with Less


As expectant parents, we wanted to eliminate plastics wherever possible, prioritize sustainable and USA made, and be as minimal as possible-which meant only buying quality products with multiple uses.


We built all these values into Mason Bottle, including a wide natural nipple shape to support the transition from breast to bottle and back.
