It WORKS!!
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 itโs worth the price to save my brain from the waves all around. Iโm hoping it helps with migraines and headaches. Time will tell!

I'm impressed
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.

Torn around tag. No use with Wi-Fi.
Nice, thin beanie for sleeping or cool weather. Fits my large head. Will have to take their word that it blocks cell and wifi radiation because, like the manufacturer states, cell signal and wifi pass thru the hat when testing with my phone and it does not serve as a full signal blocker. Docked two points because mine was slightly ripped where the manufacturers logo tag was attached on the left and right. I always seem to get irregular or slightly damaged stuff from Amazon nowadays. Repackaged returns and etc. I think my beanie was a factory discard sold on Amazon. My luck is greatโฆ

It works and blocks cell signals
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.

I got a 22.5" head but it's still too small.
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.

Poor quality workmanship for the money.
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.

Great material comfortable and it covers all the necessary areas of the head
Soft cottony material with EMF RF layer to cover the head and cool
