Are there any tests done by the company to prove your product blocks any signal?

Hello there, Thank you for contacting us. We have had our products tested by an FCC independent lab that specializes in RF/Microwave testing. The lab uses directional measurement in an isolated environment, which eliminates all external influences, ensuring no test result interference. You can see the results on our DefenderShield website under the About section or by copy and pasting the following link on your browser: https://www.defendershield.com/testing/ Warm Regards, The DefenderShield Support Team

How do you wash this hat to keep emf-proofing?

Hello, Thank you for contacting us. We encourage gentle hand washing and hanging to dry as the preferred method of caring for the beanie as continued use with a high level of agitation in a washing machine can potentially break down the silver fiber shielding material. Please rest assured that we are very confident that this would not be the case with just one use. We hope this information helps! Kindest regards, The DefenderShield Support Team

What is the circumference of the medium size beanie please?

Hello there, Thank you for contacting us. The Child Size - EMF Protection Beanie circumference is: 20-25 (inches). The Adult Size - EMF Protection Beanie Circumference is: 23-28 (inches). Hope this answers your question. Warm Regards, The DefenderShield Support Team

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 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!

Does it work?

I don't know if it works, but it doesn't keep its shape once you wash it.

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.
