Great fit and it works!
This has positive reviews so I ordered it…..Love this Faraday cap! I have a small head & was worried it would be too large, but it fits great & looks good. I’ve been wearing it around and don’t seem to be loosing my balance. Guess the EMF’s must have something to do with vertigo.

Extremely cool branding of emf protectant hat
Awesome hat I like it very much you will be happy with it. I paid like 65$ which was a little steep for this amount of silver fabric I think. I wanted it to be more on display on the outer panels too unfortunately its just the inner but its like the image shows us. If you buy white, just make sure you take care of sweat stains. Washing lightly with soap and water works well. And I got a hat protectant spray on here as well, gonna test that next time I take it with me on a run around town. On the emf protection of like wifi and 5g and stuff.. I do believe it is helping.

Large suze
This is my second emf cap, and this one is not as effective as my last one. The size is larger than expected, but like it.

Brain Protection At Work Office with 5G
They put 5G in the room where I work and I am not a fan of it as it is a very dangerous millimeter wave. I wanted to protect my brain while at work, and have started to wear this protective cap in place of my company cap of the same color. There is no logo on the front, which is good. It looks plain, but the name appears on the back and is hardly noticeable. We cannot wear any other hats, but this one seems to be OK because it looks professional and matches the company color. The outer shell appears to be cotton and the inner lining is silver material, providing protection for the brain.

Good hat.
I live in a rural area, and prefer to wear a shielded hat on occasions when it becomes necessary to venture into the cities, or in more local situations such as civic functions held in buildings with a lot of wi fi signal.This hat is nondescript, especially in grey and I appreciate that. Fit and finish are good. It blends well in most any crowd.I would prefer a snap back version as those caps tend to stay on a little better but that’s a nitpick.On balance I like this hat and am already planning to order a second to keep as a spare.

Fades Fast
I have this cap. It is comfortable and flattering. I have issues with how it has faded. I have only 4 months. See the picture for how faded the gray is. This is under normal wear and not being left in a sunny spot.
