It means peace of mind. Every piece of our clothing is certified by STANDARD 100 by OEKO-TEX®, which is a fancy way of saying:
no harmful chemicals, no toxins, nothing icky- just safe, gentle fabric for your little one.
Oeko-Tex testing goes above and beyond national safety standards. From the thread to the dye, everything is screened for over 100 harmful substances. If it touches your baby’s skin, it has to pass the test.
You get softness they love, with the safety you can trust.

Because softness matters- especially at 2 a.m. Our pajamas are made with viscose from bamboo, a fabric loved for its buttery feel, breathability, and natural stretch. It keeps your little one cool when it’s warm and cozy when it’s chilly, making it just right for sensitive skin (and sleepy snuggles).
Plus, it holds up wash after wash, because we know laundry day is always just around the corner.

Yes! IMJ fits true to size- no need to size up.
Compared to other viscose-from-bamboo brands, our pajamas are designed with a comfy, flexible fit that grows with your little one (thanks to the natural stretch). If you’re familiar with other bamboo brands, you’ll find our sizing refreshingly consistent- snug, not tight; roomy, not baggy.
When in doubt, check our size chart or reach out- we’re happy to help!
