Organic Baby Onesies

100% Organic Onesie Pajamas

The most versatile, universal staples in every baby's wardrobe are organic baby onesies. Made from 100% organic cotton, these onesie pajamas are perfect for day and night. More than just adorable, our no-fuss design is easy to change when you and your little one are on the move.

At 12|12, we’ve exchanged the chemicals found in conventional cotton onesie pajamas for their organic counterparts to make 100 percent organic baby onesies. 

Organic baby onesies are an easy way to keep your child comfortable all day and throughout the night. With organic onesie pajamas, it’s simple to make the sustainable and healthy choice for your baby.

The Softest Cotton Baby Onesies

Our onesies for girls and boys are all made from Pima Cotton, a type of ultra-soft organic cotton farmed in Peru. Pima Cotton is world famous for being soft and smooth, making it the perfect material for everyday basics. It’s so soft that you’ll be wishing you could wear it, too.

Cute Styles for Every Day and Night

Gone are the days when organic meant unfashionable. Whether you’re organizing a play date or hanging at home, our onesie pajamas give your baby the comfort they need 24 hours a day and cute enough to many moms and dads everywhere happy.

Coordinate with Other Baby Basics

We know that getting ready in the morning and at night can be a struggle. Some days, the last thing on your mind is coordinating an outfit for your baby. We made our onesies, tops, and bottom in a variety of colors and patterns that match or work well together. Whether you’re a busy parent or a baby on the move, no one wants to spend time worrying about getting ready.

Baby Onesies for Modern Moms

We get it: you have a million things to do and you need your baby’s everyday onesies to be comfortable and practical. Luckily, every pair of 12|12 onesie pajamas is built to last as they move around, grow and spill. The premium Pima Cotton that we source lasts significantly longer than traditional alternatives. Not only is it breathable but it’s also flexible so your little one won’t grow out of their size right away.

A Simple Changing Design

As moms ourselves, we understand that you need a onesie that makes diaper changes as easy as possible. For that reason, our pajamas design incorporates two, rather than three or four, buttons to make changing as fast as it can be.

Comfort and Cuteness 24 Hours a Day

Getting a good night’s sleep is the best way to keep babies and parents happy. That’s why we craft every onesie from the finest, softest Pima cotton. As cute on their own as they are with our leggings and pajamas, our long sleeve and short sleeve baby onesies are perfect for any hour of the day.
