EMF Blocking Hat – Unisex Hat with EMF Blocking Liner That Blocks Over 99% of High Frequency RF Radiation

I put my phone in with an app that shows relative signal strength and it cut it down even though it is not a closed bag/ is half open. A bit large, but just right for me as it protects right to the top of my ears. Streamline metal latch for matching cloth tightening strap that tucks in easily. Solid hat. Not wee like a ball cap but not too bulky like a trucker hat either. Middle of the road every-day hat that just looks like a normal hat and does not stand out. Recommended.

I like this hat and wear it walking around in the cities.Funny thing: a local server made some crack about “where’s your tinfoil hat” after an animated conversation about aliens or Bigfoot or whatever and I laughed, took off the hat, showed her the lining (which is not tinfoil but does have a sheen leaving no doubt it’s EMF shielded) and she and I just howled with laighter.It’s a conversation starter when you’re not feeling incognito and it’s a nondescript style that blends nicely in any casual setting.Well made, and worth the purchase imho.

It is too small for use. I'm a male who is Medium or Large usually.

My boyfriend is in Cybersecurity and Electrical Engineering — got him this as a fun birthday gift. From what I’ve done in my two weeks of research, it may or may not work. It depends on whose camp of pseudoscience you buy into. It has a silver lining for protection, is very soft and comfortable, and is well-made. I’d say it’s a great price for what it is - but I don’t know how well it performs. May try to get an EMF detector to try some at home experiments.

This is a great hat the fits well and is comfortable, but my tests show that it only blocks 50% of the EMF frequencies compared to two styles of Radia Smart hats which block 100% of the EMF frequencies. Too bad, I really like this hat. See photos

Nice hat, suitable for public appearance however not as effective with shielding as expected. For example a double layered aluminum shower cap will shield much better but unsuitable for public appearance. So it depends on your personal shielding needs, how much is needed. At home I wear my aluminum shower caps for better protection.

Great quality, a year in and still wearing it

Finally, honest EMF protection!I was looking for a hat with 5G protection that didn’t screen EMF protection and this one is great as it looks like a normal baseball cap on the outside! This is the second RadiArmor product that I’ve tested personally, the other being the phone pouch and I like that the company discloses the real EMF protection as well as the theoretical protection. I also bought a 3 axis Tenmars RF reader to test stickers and cases from other companies that ‘claim’ 99.99% reduction and it wasn’t even close. Radiarmor claims the liner blocks over 99% and that the average reduction is 90%. This makes sense since you can’t cover your whole head! With my tests I got fairly close numbers to the average with anywhere from 75 to 95% depending on location and how you hold the reader. Being that most cell phone towers are above your head, I think that number is fairly accurate.The hat is also very comfortable and doesn’t feel like any extra weight. I wear hats all the time and this one is my new favorite!
