100% acrylic toque. Made for heads 19-22.5 inches which include most toddlers, children and some adults. Please measure before purchasing as all sales are final. Verity has a 19.5' head and Adley has an 18.7' head which is considered big for 11 months and has lots of room to grow. I am MEGA picky on toques for me and LOVE the fit of these on me I just don't have a pic yet. I am looking into a smaller version depending on how these do :).
