New and Improved!!
These have an elastic like the crochet beanie kufi hats.
These are toddler through teen sized
Approx ages 3-10 years, and up.
I tried one on myself, and it will stretch to fit, HOWEVER, it presses the brim down on my forehead, so I would have to say it would be a personal preference for an adult to wear these, but up through early teens should be no problem.
