Such a cute and warm hat. I got the toddler size for my 17th month old, who's head has been above the 99% percentile her whole life. It's snug but has lots of stretch and still room to grow. The color is more brown than green as shown, that's why I'm giving it 4 out of 5 stars. It's like a brownish army green. Still like it and looks good on my girl.
