It appears that the brim is just knit - that there is no supportive frame in it. Is that true? (I hope:))
There is a 1.5 inch wide band of fleece which goes around the inside of the brim which you could say is a supportive structure (??).
This is a nice toque (Canadian for beanie) and the pictures here do it justice.
