Collection: Baby Sleep Romper

Twenty-four styles. Four product types. A print selection running from Unicorn Peach to World Soccer to Lightning Bolt. This is the most diverse collection in the Obi lineup — built for parents who want genuine variety and babies who deserve something more interesting than a plain onesie.

Bamboo Zipper Rompers offer the softest option, available in Snowflakes Bright, Hanukkah Blue, and World Soccer High Contrast. Convertible Zip Rompers convert from closed footie to open bottom as your baby grows. Quilt Rompers add textured warmth in Snowflake and Ocean Breeze. Side Snap Kimonos — nine styles — are the gentlest option for newborns, wrapping and snapping at the side without pulling anything over a fragile head.

Sizes run from 0–3M through 18–24M at $36–$40 per piece. The Side Snap Kimono is specifically recommended by neonatal nurses for the first days of life — which is why it is the most-packed newborn item in our lineup.

Prints for Every Personality

Unicorn Peach and Unicorn Pink for families who lean whimsical. World Soccer and World Soccer Pink for households where sports enthusiasm starts early. Lightning Bolt for the baby with big energy from day one. Skywriting, Endless Sky, and Seedling for parents who prefer an organic, nature-inspired palette.

Day-to-Night Versatility

For the complete range of zipper romper formats across all prints and sizes, our baby zipper rompers collection is the single destination. And for families exploring the World Soccer print family across multiple garment types, our Obi World Soccer collection brings every soccer-themed baby outfit together in one place.

For overnight footie coverage in the same bamboo quality, our newborn sleepers and infant sleepers handle the longer sleep stretches. Free shipping on US and Canada orders over $75 with code obiFreeShip.
