DefenderShield EMF Radiation Protection Beanie Cap - Blocks 99% of Wireless EMF & 5G Radiation (300Hz-10 GHz)

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

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!

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

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.

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 great…

Seems to work, will know mor
