Our Full Wire Hat brim is fitted with a stiff, metal millinery wire.  You can shape this style of brim and adjust for more sun protection. Please note this stiffer wire is harder to straighten so choose a style you will like as a semi-permanent change. Our 'scrunchable' brim is a galvanized rope crocheted into the edge of the brim.  What results is a "wavy" feminine curve that happens naturally within the design.  This brim is not as adjustable as the wire but can still be bent and re-positioned for more sun protection and styling.
