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!

I LOVE these pajamas they’re so soft, they’re comfortable and you don’t get too hot at night. true to size i’m 5’4” 135 pounds and my waist is 27” I followed the size chart for what size I got and it was perfect! I just wish they had more options for the shorts with long sleeves. I get too cold with short sleeves and the patterns i want are sold out:( but i keep checking often to see if they released more colors/if the other ones are back in stock!
