Everyday Play Organic Cotton Collection:
Fits true to size with a snug feel. For a looser fit or extra room to grow, we recommend sizing up.
Zippy Sizing Tip: Stick with your little one’s actual size! Our Zippy is designed to last 3x longer than the average sleeper, with fold-over cuffs and a comfy fit that grows with them—no need to size up.
