This is a classicly styled Sonic hat. It's interesting because it is a beanie cap, likely made of stretch-knit material. Not meant to have a rim, it's just pulled over the head. The face has no borders, leaving the 'head shape' when worn to help define the face. BioWorld made this hat, available at FYE labeled BTQ-Sonic-HDY-Sonic Zoom (if you need to call to ask for it) TisInc99 may or may not have it in stock. Availability info by Eternal Phoenix9
