Hi I'm new around here. I opened up an old Stetson box that was my grandfather's and was looking at his Open Road and was trying to figure out how this chord works. I never noticed it before, it wraps around the crown of the hat and when you take it off it is connected to one side of the crown and then forms a sort of loop like a lasso. Can someone help a brother out with this ? I'm assuming this is a wind cord of sorts.
