Jim Duncan July 09, 2021 Verified Purchase Would Recommend No big heads allowed The 100% cotton will shrink. I have about 3/4 inch velcro contact when I wear it due to my hat size. I have owned them for 1 month and hope they will continue to fit after shrinkage. If you have a large hat size they may not fit. The velcro will allow a baby's size head to work but Why?
