Our Full Wire brim style has a stiff, metal millinery wire fitted into the edge.  The hat is adorned with metal grommets to hold a leather chin strap detail.  This option also includes a matching hat string. Our "Scrunchable" brim is a galvanized rope crocheted into the edge of the hat.  Its a simple design that does not include the grommets or chin strap.  This design is easier to pack and store because of the flexible and durable rope brim.
