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.

This is a top quality emp protection hat as well as high energy electrical protection.I recommend it even when in close proximity to cell phone towersIt gmhas shielded me from high energy areas even near refineries.

Am so glad I bought this nice-looking beanie. It fits my head well and I have a fairly large head for a woman. I love wearing it indoors in the evening to help me feel more at peace knowing I'm doing what I can to protect myself from all my neighbor's WiFi in my apartment complex. My "tinnitus" was drastically reduced and I slept much better on my first night of wearing it. Especially love that it's fabric breathes and doesn't retain heat. So comfortable.

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.

I was so very much hoping this one would work for me.It is extremely well made and attractive, and could easily be used in cold weather.But sadly it is not big enough for my head. I need something larger for sure.I guess now I understand that my head is a bit largeUnfortunately I will need to return.

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.

Hace un buen trabajo.

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