About our RF EMF/EMR Protection Hats

Basic exemption - the head and brain are the most sensitive

I believe that, in most people, the brain is the organ which is the most sensitive to EMF(Electromagnetic Fields), especially to RFR (Radio Frequency Radiation). Therefore I think that the brain is the most important part of the body to shield. 

History of our RF Protection Hats
When I came down with EHS in 2004, I searched for a way to shield the head and protect it from RF Radiation that came from above, such in the case of cellphone towers and WIFI routers hiding in the ceiling of the office building I used to work in. At first, I tried to buy RF Protection hats online, but they did not work for me. Then I bought the fabric from a local manufacturer in Israel and started making hats for me and EHS friend around the world. The hats I made allowed me and other EHS people to function better, for longer, with fewer symptoms and shorter recovery time.

Nowadays I manufacture and sell RF protection Hats. If and when I can shield only one part of the body I use a hat to shield my head and brain. In addition, the hats and linings for the hats are relatively cheap, so I usually suggest to try them before ordering our shirts, jackets or any other type of clothing we sell.

General info about our collection of RF Blocking Hats & lining

It took me several years to develop the existing line of RF EMF/EMR Protection hats & lining (Radio Frequency). I first created several hats for myself, then for friends that were also EHS, and then started to manufacture it in small quantities. The products are improving all the time and our aim is to deliver the best, cheap head protection that will allow EHS people to feel more comfortable and less in pain when going outside, driving, working, walking the street and even when staying at home, all without looking like a spaceman wearing tin foil hats.

The inside lining cloth is a SHIELDON 240 © RF blocking cloth with metal fibers, and the S190 - RF BLOCKING FABRIC which is a dual layer fabric (the side touching the skin has no metal fibers in it).  When wearing it, the hat can protect an EHS(Electromagnetic Hyper Sensitive) person from RF EMF/EMR coming from above; say for example from a cell phone tower/antenna while walking down the street. 

Please note: The hats are for blocking RF(Radio Frequency) radiation coming from above and side(cell tower, wifi routers, microcells and other RF sources that are installed above you), not for blocking ELF (Extrem Low Frequency) magnetic fields!

We also recommend to use a Home Use EMF meter, like the CORNET ED88TPLUS,  in order to find and remove all in-house RF sources, find and keep a safe distance from ELF sources, find penetration points of RF radiation and use RF Protection to block the RF radiation from coming into your house.

Measuring your head size:

You should take a measuring tape and put it around your head, a bit above the ears and eyes.
The size measured in the picture below is 53.5cm
measure your head size

The Fabrics:

Today we use mainly the SHIELDON 240 © fabric, and the dual-layer S190 - RF BLOCKING FABRIC. Both fabrics are very durable and their RF blocking effect does not wear out. It is most likely the stitches will wear out before the SHIELDON 240 or the S190 will. If you are using a lining/insert and the hat itself wear out you can always remove the inside/lining and stitch it to a new hat. We try to put an extra special emphasis on making our products compact, cheap, easy to use and very durable.

In the past, we used also the SHIELDON 040 © & the SHIELDON 138 © fabrics. Both SHIELDON 040 ©  & SHIELDON 138 © are very delicate and we recommend a 300c hand wash only without any detergents.

Please note that in some of our hats the RF protection layer is stitched to the hat with a visible wire across the hat base, which can sometimes change the hat's look.

  • For EHS(Electromagnetic Hyper Sensitive) people or for people who suffer from RF EMF/EMR exposure.
  • The Hats and Clothes are designed to reduce the user's exposure to RF-EMF from his environment.
  • Should not be worn when using cell phones or other wireless devices(Press here to know why...).
  • Not for use when the RF EMF/EMR radiation is coming from below.
  • You should not put any cell phone or other wireless devices inside the jacket, pants, Shirt or their pockets.
  • If you feel any negative effect, stop using immediately. Try again when conditions are changed.
  • RF protective clothing is for EHS people but Some EHS people may actually feel worse when wearing them. 
  • The fabric contains metals, and some may react to that, make sure you are not allergic to the type of fabric and fibers. 
  • Some levels of EMR/EMF may get through the clothing and in some conditions. 
  • In addition, the clothing can, in some cases, block the body own made EMF/EMR (yes, humans also produce EMF/EMR) and can cause some discomfort.
  • Our line of RF protection clothesHats fabrics should not be worn while undergoing X-Ray, MRI, security scanners(X-ray), Security gate(ELF magnetic fields) or any other body scanners.
  • RF/MW protection clothing is not for everyone. The improvement in the user feeling is subjective and dependable on lots of personal and environmental factors and also on the way of use.
  • Please remember that EMF protection, and personal protection in particularity, is the final step that should be taking after every other step was done to reduce exposure to the minimum possible.
  • We recommend trying one item first and only then order more items. 
  • Our products are meant to reduce the exposure of EHS people to Radio Frequency Radiation from the environment  (cell towers from a distance, wireless devices and so on). In some cases, the use of our products for lab or military purposes is possible for additional protection when environmental radiation levels comply to safety standards, but the customer is required to test the products himself to make sure the products meet his requirements. In any case, the customer will be solely responsible for the use of our products. 
  • Our products are not tested for military or occupational standards and so-called safety levels.
  • Never breach radiation safety limits regardless of using or not using those products.
