This hat is created from specialized materials designed to protect the brain from absorbing harmful EMR (electromagnetic radiation) and is custom-sewn to prevent any gaps which the EMR may slip through. This ensures that your head is completely shielded; even the brim is made from these radiation-blocking materials! To top it all off, there is a strap to provide stability, eyelets to ventilate the crown and snap buttons which fixates the brim. The hat is also 100% made in Canada.
