I was never a fan of hats until I got hold of Proteck'd. I love the way it helps me stay sharp and doesn't let any emf effect me. The hat is soft on my head and doesn't feel heavy when worn for long hours. Would recommend!
They use flexfit caps. Very nice quality.
Are you a casual EMF user trying to stay healthy with style or are you someone that needs the best protection for a more aggressive EMF use?
