EMF Safety Garments

Wow! Anti-magnetic underpants! Shield yourself from microwave, radar and TV radiation. Unfortunately, they don't sell the prerequisite tinfoil hats to complete your insane person ensemble.

They do sell shielded hats on that site.

I wonder though how all this shielding is supposed to work. Granted I'm no "high-energy scientist", but I would think that metallic clothing/hats would function as an antenna rather than a "Faraday cage", intensifying rather than blocking the effect of the EMF mind-control thingys.

These sound GREAT!

Very sheer, comfortable undergarments you can wear over your regular underwear to shield yourself from powerline and computer electric fields, and microwave, radar, and TV radiation. This silver-plated, stretchable, washable nylon mesh is electrically conductive.
So in the event of touching something electrical/hot you'll get the full impact all over you
It provides EMF radiation protection by reflection.
Erm, huh?

Plus you won't get those static shocks as you used to in dry weather and your clothes won't cling to you!
No, under a layer of silver coated mesh I'm sure your clothes will just fly around freely
Fabric provides up to 35dB of shielding at 100 MHz.
That would be great, if 'up to' didn't include the number zero. And isn't dB a measure of volume or air pressure or something?
Made in USA.
Much better than those nasty Taiwanese foil pants
Surround what you want to protect!
There aren't any bits of my body I don't want to protect actually

Specify desired size when ordering: S · M · L · XL · XXL
We recommend that you order a size larger than you normally wear, so that you can put the Silver Lining garment over a cotton undergarment, to avoid direct contact between your skin and the conductive fabric.
We also recommend not telling your friends or family about the fact that you are wearing 300 dollars worth of electrical shielding as they may think you are mental

Is it me or are we all in the wrong jobs? Maybe we should be embracing these products so we can retire young?

Well, dB is a measure of power ratio. 35 dB of shielding would mean that it reduces the RF energy by a factor of 10^(35/10) at 100MHz if they did their work right.

That's a factor of 3160, give or take.

Or the square soot of that in amplitude (instead of power) terms.

dB SPL is a measure of RMS energy in a sound wave. There are two definitions, too, for that, that differ by 74 db.

Having said all that, I have to agree, where's the tinfoil hat and the "comfortable hands-off cellphone attachment"

I don't worry about thouse dangerous electric waves since my clothes are guaranteed to reduce the signal 0 dB.

It provides EMF radiation protection by reflection.

A faraday cage blocks EMI and high voltage by providing a path to ground via the metal in the cage NOT by reflection.

It says the EMF gloves do not require to be grounded. Which Is a load of BS on many different levels. If the gloves are not grounded any RF or charge would be grounded via your body.

The only way to truly block RF radiation (to which they are acually refering to because the earth's magnetic field is constantly surrounding us as well as cosmic and solar radiation and the natual radioactivity of the earth) is to encase your self in metal from head to foot without any gaps for RF to leak in. Consequenty oxygen will not "leak" either. But then that would probably solve everybody's problem.

Unh, if I float a faraday cage in space, it will still block static e-fields just fine as far as its insides are concerned. You're mis-summarizing how a faraday shield works. Grounding does something different. Look, the earth floats in space, it's not grounded.

Well, you're leaving out wavelength effects, and the fact that you won't block magnetic fields with most metals, either. Again, you're oversimplifying a complex subject.

Actually, no, you don't have to "block" things that thoroughly. You might want to look into "matched absorbers" and the like.

Wrong. Clothing does have some small loss, if you wear any. Even the hair on your skin has some small loss.

But that's reduce 0dB, not reduce to "0dB" although the latter really has no meaning without a reference level, which is not "zero energy" anywhere in the known universe. Even "empty space" is at 2.7K.

Static electric fields are different than RF. A faraday cage floating in space will still block RF. High frequency current tends to remain on the surface. See RF wave guides. The earth situation refers to what is called a floating ground. See floating or self refernceing ground.

True, it is a over simplification meant to be facecious.
If you look up MU metals you will find that magnetic fields can be redirected away from an area. Mu metal is an alloy of nickel and copper (I think) that is used primarily in Hard drives (in the read/write head actuator) and high energy physics.

Again, an over simplification made in the line of sarcastic humor.

Yes, I'm well aware of what a floating ground is, or a constant potential situation, etc. Your whole point about this silly-wear needing to be grounded is the problem, no, it doesn't have to be grounded. Of course, under almost all environments people face, it's still silly-wear.


True, it is a over simplification meant to be facecious.


Now, I think, we get to the heart of the problem. I couldn't tell you were being facetious.

I've designed a 5-layer shield made of mu-metal and copper. For what is a long story, but it was inspired by the need to get to 20 bits in a noisy space with no good ground.


Again, an over simplification made in the line of sarcastic humor.

Well, then, that just wasn't obvious to me.

I can easily understand how the OP can inspire sarcasm, of course, you simply appeared to be mis-stating some shielding basics. Many people might take what you said at face value.

Point well taken.
