I was worried hats would slide off my newborn but this one stays put like a little swim cap and actually covers her ears. The knotted top means I can loosen it as she grows instead of buying new ones every month.
The tagless inside is a small thing but it means no scratchy label rubbing on my daughter's forehead during naps. It covers her ears just enough without slipping down over her eyes, and the organic cotton feels soft right out of the wash.
The knotted top adjusts so easily that we've been wearing it since the newborn phase, and the organic cotton is incredibly soft against her skin. It fits snug enough to stay put during walks but never leaves red marks, and I love that there's no tag to bother her.
