Softest Baby Onesie

We set out to create the world’s softest baby onesies

At A Muffin in the Oven, we set out on an adventure to create the softest baby onesie ever. Our babies sleep, play, laugh, and smile in those little full body onesies we all know and love. Naturally, we wanted to make sure they were super-duper soft, clothing so soft, your baby will feel like they’re back in Mamma’s belly. Now, that’s a big claim, so it’s only fair we drop some facts to back it up!

How did we make the softest baby clothing?

Okay, so we had some help along the way. Actually, a lot of help! Our founders, Clelia & Alberto, are thankful to have worked with some of the world’s best textile engineers, fashion designers, and sewing masters. Leaving no stone unturned, we found the fiber Gossypium barbadense, aka Pima Cotton, which is one of the finest cottons in the world. We went step further. They chose only genuine, organic, and verified TRU-Pima Cotton to make sure we gave your baby the best quality. Our moral fiber – pun intended – was all about using the best cotton for our baby clothing.

It was a perfect match!
