Important Features to Consider When Purchasing EMF Protection Underwear


If the underwear don’t provide EMF radiation protection, what’s the point?

Silver is the common metal used in EMF protection clothing because it’s soft (flexible), with high electrical conductivity and antimicrobial properties. So generally, you want to look on the listing or packaging for a higher level of silver.

Some of these companies take it to the next level and offer independent product lab testing to prove their effectiveness.

These lab tests can involve varying levels of frequencies (MHz) then complete several shielding effectiveness tests on the fabric, such as a noise floor measurement, direct measurement, dynamic range, and steel panel isolation. At the conclusion of these robust tests, the lab can provide an “effectiveness” percentage.

It should provide complete protection and should have shielding features. We all know that excessive radiation exposure makes sperm count lower and fertility rate goes down with time.

The best EMF protection clothing companies will publish these results so you feel confident the underwear you’re purchasing is doing its job.


If the underwear fold over at the waistband or ride up your legs, you’re not going to wear them. If they’re itchy, hot or have a bad fit, you’re not going to wear them.

Not wearing EMF protection underwear provides zero protection from radiation. So comfort is a top consideration.


This is pretty common sense but some companies don’t sell a full spectrum of sizes. Also, be sure to check out sizing charts. A “large” from your current brand may not be the same size across brands.


EMF protection clothes run more expensive than clothes at the local retailer. The most obvious reason for this is the silver. Silver, while ideal for EMF attenuation, isn’t the cheapest. And the most effective underwear at blocking EMF radiation are those with the higher percentage of silver.

But! That shouldn’t mean you need to take out a small loan to safely carry a cellphone in your front pocket. Our top rated underwear are also among the most competitively priced. This is just a guess but they’re likely benefitting from economies of scale. The more they sell, the more bulk pricing becomes an option, lower costs, etc.

Anyways, we always consider cost in our rankings. So check them out below.

After considering the options on the market today, we’ll take a deep product by product look at the best on the market.

Lambs Faraday Boxer Briefs

Lambs Faraday Boxer Briefs offer the best of all worlds. Highly effective at blocking EMF radiation, comfort, sizes from small to XXL and the best prices. In fact, the higher quantity, the cheaper each pair becomes.

If you prefer a trunk without a fly pouch, Lambs has Radiation-Proof Trunks also.


  • 99% EMF attenuation – 360 degree silver fibers (more on this below)
  • Soft – 39% silver, 44% cotton, and 17% polyester
  • Breathable, no roll waist band, and antibacterial
  • Cost effective

Women’s Lambs Faraday Cheeky Brief

Lambs released a line of women’s EMF protection clothing, including these Faraday underwear. These offer the same EMF protection from wireless radiation. Offering comfort, sizing from XS to XXL and machine washable, these are a great option.

How Lambs EMF Protection Works

Lambs provides laboratory tested Wavestopper technology. Wavestopper technology, according to the Lambs website works by utilizing a conductive wire-mesh material. Electromagnetic radiation (EMF) cannot pass through holes in conductive materials that are smaller than their wavelength.

This conductive material is silver. As we’ve discussed extensively, it is a highly conductive material that is also soft and antimicrobial, so it’s ideal for clothing.

When radiation meets the conductive wire-mesh material, it’s reflected to the outside instead of permeating the material.

Lambs utilizes this technology by sewing the silver inside the cotton to provide the wire mesh radiation shielding.

How Effective Are They?

The great news is you don’t have to just take their word for it. Lambs tested their EMF technology in the same lab that certifies NASA space suits.

Read the full report here.

Wavestopper technology is lab tested to provide 99% EMF protection from microwaves, which includes wifi radiation, bluetooth, and very importantly, radiation from cell phones.

What Customers Say

100% of customers on the Lambs website  would recommend these products to a friend. Some consistent remarks about them include:

  • Comfortable with a good fit – not too tight and not too loose
  • True to size
  • High quality and durable
  • Machine washable

A customer also noted they would like to see them in the color white. Right now they’re available in black, blue and red.

Shield Signalproof Apparel Boxer Briefs

Next on our list are the EMF underwear from Shield Signalproof.

These underwear are also effective at blocking EMF radiation, comfortable, and offer slightly fewer sizes from Small – Large.


  • 99% EMF radiation attenuation
  • Soft – 45% Cotton, 35% Silver, 20% Polyester 
  • Antibacterial and anti odor
  • European sizing


  • Lower percent of silver in fabric
  • Ships from Europe (they do offer worldwide shipping but the order minimum might be higher to qualify for it to be free)
  • No discounts for ordering in bulk

A note about these underwear is they’re designed in London. If you’d prefer a European fit – and sizing, these might be for you. They have a shorter inseam so they ride higher on the leg.

If you’re American, be sure to check out the size chart and translate as necessary to inches.

How Shield Signalproof Apparel Works

Their underwear are made of a silver fabric that attenuates EMF radiation. Their site says their fabric blocks frequencies from 10 MHz to 6GHz. This covers a wide range of wireless frequencies, which generally range from 700 MHz (4G) to 850 MHz (new 5G).

So not only can you keep your cell phone in your front pocket, you’ll be protected when 5G rolls out from coast to coast.

Further, the underwear don’t have a pouch so you’re receiving 360 degree from this product.

You will notice that these underwear do contain a lower amount of silver in their product, 35%. So although they do still offer that their underwear attenuate 99% of EMF radiation, it would be great to review an independent lab test of the claim.

An interesting side note about this company is they are funded via Kickstarter. Kickstarter is a funding platform where people with ideas can present their ideas or products. The general public can then offer funding to the products they think should be made, or back them. Signalproof started as a Kickstarter. Clearly, people see a need for this kind of EMF radiation protection.

What Customers Say

Unfortunately, there isn’t a review section on the Shield Signalproof website.

Shield Your Body (SYB) Boxer Briefs

Last but not least are the SYB Boxer Brief underwear.

Shield Your Body or SYB is a high quality brand that manufactures their underwear in Canada. They’re effective at providing EMF radiation attenuation, and offer a good range of sizes from a medium to XL.


  • Up to 99% EMF radiation attenuation
  • Soft – 42% silver, 53% cotton, and 5% nylon 
  • Anti-microbial, anti-bacterial and anti odor
  • Lab tested & lifetime warranty


  • Expensive

The sizing of these EMF underwear ranges from medium (32-34) to x-large (40-42). Another note is this company stands behind their product. They offer 30 day returns and a lifetime warranty. The major downside to these underwear is the cost. They’re a premium brand at a premium price.

How SYB Protection Works

SYB is a company that focuses on the science of EMF radiation and how to most effectively protect yourself with top-quality products. These underwear are no exception.

Similar to other products reviewed here today, SYB products work by creating a mesh of conductive material. Again, this is silver. The highly conductive nature of it makes this an effective method of reflecting the EMF instead of it passing through to your body.

These underwear include 42% silver.

SYB also ensures complete wrap around coverage to deflect EMF. It’s good to know they don’t have a front pocket, which is part of the 360 degree coverage.

How Effective Are They?

SYB offers that their underwear provide EMF attenuation effectiveness of between 15 and 35.9 dB tested between 15MHz to 40GHz. As mentioned earlier, this encompasses the frequencies of 5G. So 99% attenuation can be achieved.

SYB says their products are lab tested but after a search, I cannot find a copy of the actual report to confirm these numbers.

What Customers Say

Some of the remarks on the SYB website include:

  • Soft and comfortable – not too tight but might be a little loose around the leg
  • Good fit
  • Expensive
  • Relieve for the EMF radiation attenuation

Where Are the Women’s EMF Blocking Underwear?!

That’s an excellent question! Where are the women’s EMF protection underwear?

Finally, in 2020, Lambs addressed this and put out a line of great women’s underwear.

Wrapping it Up

EMF and EMF radiation is all around us. Cell phones in front pockets are particularly prevalent and we hope the products here will protect you and your loved ones from EMF radiation in places where EMF radiation shouldn’t be for your health! Right now these products focus on men but women’s products are on the way.

I hope this article is helpful to you and I’ll be updating it as more radiation blocking technology hits the market.
