This nearly new winter hat has a bit of British styling (IMO) with a more slim tear drop crown with equal heights (4 1/4 inches) in front and back, and the eight ventilation holes. Also, the brim is 2 inches wide at the sides and 2 1/4 inches front and back. The inside hatband is 22 1/2 inches. Fully lined crown is nylon. This is a very robust hat that holds it's shape very well.
