This tie-on headwrap is made with high-quality stretch fabric and available in two sizes: newborn-specific and one-size-fits-most. The length of each headwrap varies, depending upon the characteristics (stretchiness, thickness, etc.) of stretch fabric used. If you're looking for a headwrap that will fit your newborn's little head nicely, the newborn-specific size may be right for your little one. If your babe is three months or older, we recommend the one-size-fits-most headwrap.
