Review: Sharp hat, maybe it blocks radiation - Nice hat. Does it really stop wifi radiation from frying your brain? Who knows? But the thought that it might is sorta comforting. I have two of the caps and two of the beanies. Wear them all the time, like the proverbial nut job with the tin foil hat. No transmissions from aliens yet, though.
Review: Great quality! Superior functionality - I did some research into the different brands for getting EMF blocking clothes, and I chose the HAVN hat because it seemed the most legitimate, and very high-quality. After wearing the hat for the past two weeks, I’ve been very impressed with the quality. Considering the material costs as much as cashmere to produce, the price made sense and it’s worth it to know that it truly works. It’s very comfortable and well made. It fits well. I like the style, It’s very clean. and I truly believe the functionality is superior to other brands. I will definitely be buying more HAVN gear in the future.

### ⭐ Poor quality
*by J***B on January 1, 2025*

I was so excited to receive your EMF protective cap until I started inspecting it. As soon as I unpacked the cap the button on top popped off. When I put the cap on it was evident the bill of the cap was lopsided. To much money for a cap that’s 2nd or 3rd quality. I don’t recommend the cap!
