I just found out Bell is using a scanning process to make a Star custom fit to one's individual head shape on a limited basis. I hope I'll be able to take advantage of this technology advancement sometime because I wear a cochlear implant and no helmet I have tried has room for the BTE so I have to ride in silence.
