Received hats that appear to be knock-off Richardson hats. Inside plastic on these hats will cut your head when removing the hat. We've never had this problem with any Richardson hats before, and never had problems with OpenTip before. Sent samples back to them and they still will not admit that these hats are defective. Anyone trying these hats on can see/feel that they are defective. The black part (shown in photo) is almost equivalent to chicken wire! Buyer beware.
