Because of special silver shielding fabric inside the hat. Every signalproof hat is made out from the outer layer and inner layer. Inner layer is always the special shielding fabric which consists of the pure silver that assures the highest performance and has other advantages like antibacterial, antimicrobial, antiodor and antistatic feature. There are also cheaper materials for this purpose, for instance copper or steel but they don`t last long time, don`t have additional features or inhibit alergy. And silver is silver.

The signal around must be stronger than the hat is able to stop. Signal-blocking hat is not a magic. It`s the pure physics. Special shielding fabric can shield only the particular amount of electromagnetic radiation. Generally, the shielding effect is up to ≈80db. If the signal around is more than this value, what is the very normal and common situation, your cell phone covered by hat will be ringing. But the received signal is reduced almost to the null. It`s the same with waterproof, windproof, bulletproof or other proof materials. If you start shooting from the machine gun to the bulletproof vest, it will fail. If you expose the waterproof jacket to the storm, it will fail. If you expose the windproof pants to the hurricane, it will fail

Yes, it works thanks to the special silver shielding fabric inside. It has standard shielding effectiveness 60dB-80dB from 10 MHz to 3 GHz. Silver is also antibacterial, antimicrobial, antiodor and antistatic. Generally it can`t completely protect your body against signals because it should be covered from the top to the bottom. The shielding fabric is tested and it blocks High Frequency & Low Frequency electromagnetic radiation.

Our hat is not the improved version of “tin foil hat”. It`s inspired by actual situation and studies. Until now, we`ve known the waterproof, windproof or dustproof feature. Now it`s time to introduce the signaproof feature into fashion. Shield is more beautiful, comfortable and sophisticated hat than tin foil hat.

Barely. Dots or ticks on signal indicator are not accurate and each phone model reacts differently. It takes also a longer time until the phone realizes that he is losing the signal. The next problem is that you can not see the reaction of your phone inside the apparelt. If you put it in and then you pull it out you will not see the real status of the indicator. You would have to be inside the apparel with your phone. It`s like testing the waterproof bag under the water. You simply can`t open the bag under the water to check if it is dry. And also the signal strength varies and depends on where you are. If you are very close to the emitter or antenna, then your signal indicator will maybe not drop. The thing is that the apparel can`t reduce

Silver fabric is weaved by silver fiber. It's soft, stretchy and comfortable to wear. Commonly used for making anti-radiation cloth or home textiles. We incorporate it into our hats as a middle layer or some of our products (underwear) are entirely made out of the combination of silver and cotton fibres.

- Anti Radiation Performance

Silver has good conductivity, the properties of conductive metal is generally several times and even hundreds of times, based on the principle of conductive anti-radiation. Woven with silver fiber fabric is an excellent material for shielding electromagnetic radiation.

- Antistatic Property Of Antistatic (ANTI-STATIC)

Due to the highly conductive silver, anti static 5000v, with electromagnetic shielding func
