Many can be recreated with some thought and creativity.
For example, this one is knitted flat (the cables run around the hat, not up and down) and then seamed.
The ribbing is created by picking up stitches on the edge of the bottom cable and then knit to length.
The cable is readily available.
You can find hats that are constructed that way.
