Actually works
I was looking for a hat made from bamboo viscose and none were, but this one had a bamboo liner. I bought it because I am interested in EMF and wanted a bamboo hat. It says that just sticking an EMF meter inside it isn't a good way to test if the hat blocks EMF and RF. I did it anyway and it actually did block almost all of it. While wearing it you feel like everything is quieter in a sense. Its hard to explain the feeling, but you can tell it makes a difference. I held my Geiger counter to it as well and it was not radioactive. I only say that because some products from China have Thorium in them and are radioactive. Honestly, I'm impressed with the quality and this hat is about $30 cheaper than many other EMF blocking hats .

Golden Kocoon caps are extremely well made and durable.
Golden Kocoon EMF cap is extremely well made and I am very picky about caps, I've had to buy three of them recall's friends keep wanting them after they try them on, HaHa. They keep their shape unbelievably even when it's raining, and the fastener, it retains the sizing, even when it gets wet. Love it!!

Great fitting cap, a couple issues...
I really like this cap. It fits well, and the meter I have shows there is a difference. Challenge 1. Price - too expensive for what it is. I understand the EMP properties, but the cost of materials should not equate to this price. That is partially why I won't be buying more. Bringing me to challenge 2, Personal preference is that I want a felcro patch on the front and a long skinny one on the back with one on the top as well. If there were appropriate velcro patches, I would have bought more, regardless of whether I think they are "too expensive" or not.

Comfortable hat
I like this hat. It’s comfortable. I haven’t tested if it blocks all the bad stuff, but I like wearing it and like that it’s blocking all of the radiation and cell signals. It’s fashionable and comfortable. Look no further.

Please test yourself before you take company word for it.
Yes, it seemed to have silver in it, but in my testing, it wasn't that effective. If you are serious about blocking EMF please have quality emf meter and test yourself. Do not take word from these companies. I have thrown this hat away and am using another brand that actually blocks most EMF. Maybe I got bad example or maybe this company is misleading us?

Finally - back to just the voices in my head… that’s nice.
After the aliens tickled my me nugget I got CNN streaming in my head! This blocks it perfectly!

Makes my head hurt due to fit
The hat is so sturdy that it makes your head hurt after wearing for over 20 minutes for me.

Top notch materials and craftsmanship
I ended up not being able to fit the cap, which is terrible because it's extremely high quality. The materials, stitching, and finish work are all top notch. I have a very large head, and this cap almost fits so don't let my experience discourage other cranially endowed people.
