Mason Jars, Reimagined

For this Stainless Steel Mason Jar we took our inspiration from the classic 16 oz. mason jar, but make a few modern updates. This stainless steel mason jar weighs only 3 ounces, three times less than the 16 oz glass mason jar.

We also rounded off the sides to make it cupholder-friendly, and easy for even little hands to hold, while still keeping the same capacity.

Grows with your Family

We loved glass bottles for the baby stage, but found that we needed an ultra-tough material for the toddler years. So we created this stainless steel mason jar to be compatible with all Mason Bottle products—and indeed any regular-mouth mason jar attachment.

Use as a Baby Bottle

If you’ve already used our glass baby bottles, you can simply add those same pieces onto this stainless steel mason jar. From daycare, to the playground, use it anywhere that glass may not be allowed/preferred.

Use as a Sippy or Straw Cup

If you already have our silicone squeeze pouch or straw tops, simply add the top to this stainless steel mason jar to make a sippy cup or straw cup.

If you haven’t purchased either of those products, just buy our Stainless Steel Bottle here for the best deal.

Use for Big Kids and Adults

After the baby stage, upcycle our plastic rings and silicone disks to store snacks. It’s so lightweight you could take it camping. Or add any straw or sipping top you like.
