Vinsatin2 Pcs Protection Hat Slouch Beanie for Women Men, 5G, 4G, Rf Shielding Hat, Wi-Fi Protection Skull Beanies Cap, Black, Gray

Very large sized, good for sleeping, big enough to pull over your eyes. Not something I would wear out of the house. Good for big heads. Lightweight enough that you won't overheat. Great price for what it is, 1/4 of the price of my other EMF beanies.

I was charged for 2 sets and only received 1 set. Don't see a way to contact seller. Not happy. Seller made this right.

Fits well, on my large head. It does not fall off comfortable to wear if I happen to have one sitting on the seat of my car, and I put my phones on the hat, i’ll have to re-login to my work account app. So yes they work and do the job they’re supposed to do Protect my head. Love my beanie.
