This hat is adjustable. The knot is tied, so it can be tied tightly for a smaller size and undone for a larger size.
The cool thing about this baby hat—other than the fact that it’s USA made + sewn with soft organic cotton is that the babe will smile + giggle because the knot adjusts up and down to fit baby's head. It’s machine washable, lead, phthalate and flame retardant free so it won’t irritate baby’s skin. And, you get kudos for your savvy sense of humor while helping save the planet.
