DefenderShield EMF Radiation Blocking Beanie Cap - Blocks Wireless Radiation (Gray)

Fit is great (normal woman sized head) and I put my phone in the hat and the call went to voicemail!!! This thing works! Expansive but it’s worth the price to save my brain from the waves all around. I’m hoping it helps with migraines and headaches. Time will tell!

I took a chance and order two beanies without reviews, so I didn't know what to expect. As soon as I received them, I immediately check them by placing our cell phones in side, and couldn't receive calls what so ever. So I have to say, they work. Now for size, I got both adult sizes. They are a decent length and can fold to fit over my ears. I'm pretty much a normal size, but my hubby he has a bigger head than I. Mine was a bit snug, and he had to stretch his out a bit, then slipped it on. He likes it. After sleeping with it, It didn't slip off while tossing and turning, so I guess i like its a little snug. Its been 2 days now of wearing and its stretched out a bit and fits perfectly. I'm glad I bought them and keeping them.

The idea is great but skimpy on the actual hat. Too small for my small head. I can’t imagine someone with large head. Have to keep pulling it down.

Very tight fit on my small head, and the Faraday fabric did not stop any transmission of signals under my testing

Not gonna lie. I was expecting this to be garbage and not block any signal at all. But I put my phone in it and held it shut while my wife called my phone. It went straight to voicemail. Then I opened the hat but left the phone in it. It still wouldn't ring through. When I pulled the phone out, I saw that sure enough it didn't have any signal in the hat. So then I had my wife call my phone, I answered, and then while it was connected, I dropped the phone into the hat. The call disconnected immediately. I'm impressed. I only got the hat today, so I can't speak to its durability. But it certainly does what they say it does. My only complaint is that its a big small. But I also have a freakishly large head. It would be cool if they made a freakishly large size for people like me.

Product looks like it protects, but it's too small and the silver shielding doesn't go down enough to cover the forehead or the lower side of the back of the head.

Great beanie for my baby it works well and is legit. I did the phone test and it really blocked the emf. Recommend and going to get one in adult size for me. Happy with this purchase

Great comfy hat, sleep seems to be better.

The stitching that holds the inner lining in place (the most important part for EMF protection) keeps coming apart and I have to restitch it by hand. When you pay this much money for a toque you don't expect it to fall apart.

Soft cottony material with EMF RF layer to cover the head and cool

Cell phone rang while in hat, product is no good.
