Why Parents Love It

Less Fuss, More Sleep

Unlike traditional onesies that require bending baby’s legs and exposing their body to the cold, our patent-pending EasyGlide Zipper system:


Keeps baby cozy during changes—so they’re less likely to wake up upset.

Reduces nighttime crying & kicking—helping babies fall back asleep faster. (Silveira et al., 2021 | Lukowski et al., 2015)

Helps Maintain a Stable Sleep Temperature

✔ Traditional onesies leave baby’s legs exposed during changes—causing temperature drops that wake them up.


✔ Our Convertible Onesie keeps most of baby’s lower half dressed, reducing sleep disruptions. (Okamoto-Mizuno & Mizuno, 2021)

--

More Convenient Than Any Other Sleepsuit

👕 Easily converts from a full sleepsuit to a long-sleeve bodysuit—no extra outfit change needed.


👶 Designed for tired parents—Intuitive design becomes second nature after a few uses.

Safer & Softer Than Other ‘Organic’ Baby Brands

✔ Made from premium long-staple GOTS-certified organic cotton—which is softer, more durable, and pill-resistant, unlike regular organic cotton.


✔ OEKO-TEX Standard 100 Certified Dyes—meaning not just the fabric, but also the color treatments are completely free from toxins.


✔ Premium YKK EasyGlide Zippers—smooth, long-lasting, and designed with 2 protective barriers to keep baby’s skin safe.

Make changing time easy as with these 4 simple steps:

  1. Unzip: Unzip the legs—no need to bend out baby’s legs!
  2. Secure: Use the soft Velcro tab to snugly secure the Convertible’s legs around your baby's legs, ideally a little above the knees to keep in place during the change.
  3. Change: Change the nappy while baby stays cozy & calm.
  4. Zip Up: Zip back up in seconds—fewer stressful moments, more sleep.

Putting the Convertible
on your baby:

  1. Start by opening all the snaps. Think of the Convertibles as pants—simply slide your baby's legs in first from the neck.
  2. Next, gently pull up the upper body section and guide your baby's arms into the sleeves. Snap everything into place, and you're all set!
