Overview

We built a unisex hat that actually stops radiation. Inside is a breathable liner made of woven silver fibers that blocks over 99% of high-frequency RF and millimeter-wave radiation. That includes the stuff coming from WiFi, cell towers, and 5G.

Lab Verified: Real World Vs. Lab Material

Let's clear something up right away.

Our breathable silver fabric blocks 99.9% of high-frequency RF in a controlled laboratory setting. But what happens when you put it on your head? In the real world, the average reduction inside the hat is about 90%.

Why the difference?

Think of RF radiation like light from a flashlight. If a tower is off to the side, some of that "light" bounces up from the ground or a wall and enters from underneath the brim. This hat protects your head, not your entire body. Unless you plan on walking around inside a fully sealed metal box, you can't block 100% of everything.

Integrity: Watch Out For The Hype

A lot of EMF companies love to shout about "99% reduction." What they aren't telling you is that they are only talking about a tiny patch of material, not the actual coverage you get.

Buying an EMF sticker or a small pendant to protect your body is like holding a waterproof coin over your head and expecting it to keep you dry in a rainstorm. It makes no physical sense.

We don't do gimmicks. We design products based on actual shielding physics, giving you real, measurable protection where it matters.

Sizing & Care

  • Sizing: This is a unisex design with an adjustable strap. It fits most heads comfortably, but if you usually buy XL hats, it might be a tight squeeze.

  • Care: Silver is naturally antibacterial, hypoallergenic, and odor-resistant. It rarely needs a wash. If you absolutely must clean it, hand wash and hang dry only. The silver will naturally tarnish and change color over time. Don't worry—that's just chemistry, and it won't lower the 99% shielding performance one bit.

How to Test Your Hat

If you want to test this at home with an RF meter, you have to do it right.

  1. Get the right meter: Use an RF meter that measures high-frequency microwave radiation (WiFi, cell signals, 5G).

  2. Find a hot spot: Stand near a WiFi router or a window facing a cell tower so your meter gets a strong baseline reading.

  3. Measure inside: Place the meter's sensor completely inside the hat to see the drop.

Quick note: This hat does not block low-frequency magnetic fields (measured in milligauss or mG) from things like power lines or breaker boxes. It is specifically engineered to shield against wireless communication frequencies.
