HAVN EMF Blocking Hat for Men & Women - Adjustable Faraday Cap with WaveStopper Silver Shielding - Blocks 99% of WiFi 5G Cellphone Radiation - Breathable EMF Protection - Black One Size

Nice hat. Does it really stop wifi radiation from frying your brain? Who knows? But the thought that it might is sorta comforting. I have two of the caps and two of the beanies. Wear them all the time, like the proverbial nut job with the tin foil hat. No transmissions from aliens yet, though.

I love this cap. It fits really well, feels comfortable, and gives me peace of mind knowing it’s helping block EMF waves. Simple, stylish, and exactly what I was looking for. The fit is perfect and it is adjustable.

I was so excited to receive your EMF protective cap until I started inspecting it. As soon as I unpacked the cap the button on top popped off. When I put the cap on it was evident the bill of the cap was lopsided. To much money for a cap that’s 2nd or 3rd quality. I don’t recommend the cap!

I purchased this in the beanie and I love it so much. My head feels clearer than ever and I wear either on.

Excellent product. Delivery on time. Works just as it says.

I own a Lambs beanie and it's been exceptional at stopping those pesky EMF waves. I know this because I am nerdy enough to own an EMF meter. You can test it out yourself though. Just put your cell phone under or inside the hat and have someone try to call you. The signal won't get through. I saw this baseball cap from Lambs and knew I had to have it. It's very basic and boring, something you'd wear to the gym or yoga class. But, really, that's the point. If it was a real tinfoil hat or otherwise looked weird, you wouldn't wear it. This is designed for everyday use- at home, on the golf course, camping, hiking- anywhere you'd wear a baseball cap and want to be protected. Lambs linings are the reason they've got such a good reputation for EMF-proof apparel. Their linings contain a lot of silver and can block 99% of WIFI and 5 G signals. That's about as good as it gets. The design is solid and classic, well-stitched. Lambs costs more for a reason. If you aren't sure whether brain damage from EMFs is a problem in America, all you have to do is listen to political speeches for a an hour. I am not sure if this cap will protect your brain from propaganda and misinformation, but it couldn't hurt.

Seems like it’s built well but doesn’t fit large heads

Bummed it was cheaply made. I hope they will make them well someday.

More people are becoming aware that the intelligence agencies can scan and extract information from the human mind using microwave 'cyclone' or similar radiation patterns at very high frequencies and high gain levels. If the Pterodactyl or Salamander programs are targeting you, this hat will not help. If you are aiming for general purpose cognitive privacy in public spaces, border crossings and airports, I think that this hat will offer some help. I wear mine in public spaces now and appreciate the protection that it offers. Again, it depends on your adversary and application. The hat is well made, good quality.
