Golden Kocoon®- E-M-F Organic Cotton Beanie with EcoShield™ Tech Bamboo Lyocell Faraday Fabric Silver Liner- Adult Size Hat in Black -5 g, BT, Smart Meters & WiFi- Cocoon Cap

So I haven't actually tested the efficacy of the emf or wifi blockage, but I can say it's very comfortable. I'm a small woman with a small head and it fits great. Like others have said, it is small, so if you have a larger noggin, I wouldn't suggest it, or if you're OK with a tight fit, then maybe it's for you. I wore it last night to bed to see if it affected my sleep, and while I can't say for sure, I feel like I slept great and soundly for once. I'd def buy again and recommend.

Been using for maybe a year, great quality product overall. I looked up how silver fiber is made and supposedly it is like melted/bonded in to the fibers. So I've just thrown this in the wash like normal and it will still have the same effectiveness.

This is the warmest cap I’ve ever had. It looks and feels great. Very high quality

Nice hat but I agree with reviewers who find it quite small. My hat size is 7 1/8 which is not exactly large. I liked the hat at first although it was snug. But it becomes uncomfortable after an extended time of wearing.

If you're a targeted individual like me, don't bother to purchase this product. I had high hopes at first since as the ad suggested, I checked it with a decent meter and not a cell phone. I have a GQ EMF-390 and placing it in the beanie did show it to curtail most of the signal mix in the immediate surroundings. But after trying it several nights thereafter, it did not stop the remote neural monitoring or voice to skull being perpetrated on me by my antagonists every evening. (I even heard them say, "He's got something over his head.") My girlfriend said she's buying me a faraday blanket for Christmas, but I'm anticipating it to fail as well in light of the finding I had with this beanie. I don't know what they do to circumvent this kind of shielding to still get through; perhaps they just increase the output power of their signal, or it's a different kind of signal (ultrasound, scalar, or beyond 5G?) that this type of shielding is not effective against. But again, if you're a targeted individual looking to shield from RNM and/or V2K, don't waste your money here. I'll try to be a little fair and make a notation here that it probably deserves five stars for the pedestrian signals I do see it being effective against. Regardless, here's wishing you, your family, and friends a joyous and meaningful holiday season.

My hat just arrived and I cannot wear it yet because it smells heavily of toxic Amazon sanitizing spray. For those of us with MCS (i.e. highly allergic to fragrance/scents) this is a no-go. Hopefully several days of soaking in baking soda water will get rid of the smell and I will be able then to try it out.In the meantime, it seems well-made and as others have said, the fit is snug (for the brief moment I tried it on just to be sure it fits before plunging it into baking-soda water). I'll update my review once I'm able to actually wear the hat.

I never leave reviews Unless it is terrible and this is quite the opposite. I feel like I have a big head and this fits snugly, but, right, not constricting. Seems to be high quality, nice style, and if it protects my brain from EMFs it sounds like a win to me.

I had been always feeling like I am half awake and all the energy gone soon after arriving at our city home from where I spend months at a time in the country. It got so bad to where all I wanted to do was sleep only a week after arriving. It would feel like I had just recovered from having surgery with anesthesia and just wanted to sleep and felt low energy.Problem solved.I have been using this now for a month staying in the city and I am feeling like myself and not a drugged person any more. For those who suffer from microwave sensitivity I would highly recommend using this. I even wear it to sleep and fortunately it is the cold season here and gives me the additional comfy feeling even at night.
