Made from our ClimaCuddle® fabric, a Merino wool and bamboo rayon blend, this award-winning zipped baby romper is soft and built to move with your baby through play, tummy time, and sleep.

Merino wool naturally keeps temperature steady while bamboo rayon lets the fit breathe through every kick and stretch.

The temperature-sensing sticker shows their comfort level so you can check from the sleep sack without touching.
