(2 customer reviews)



Here are the fine anti wave caps requested by many customers, concerned about protecting their brains during the night.
The anti wave protection of this beanie, 50dB, is identical to that of our other beanies, but the weight of the cotton is lighter: 80 gr/m2 instead of 120 gr/m2 for our other beanies.

How did we design the anti wave thin hats?

  • Shield composition: 80% spandex, 20% silver.
  • Composition of the organic fabric: 95% GOTS certified cotton, 5% spandex
  • 50dB
  • Thanks to the three-layer construction, a layer of anti xwave fabric sandwiched between two layers of GOTS-certified organic cotton (inside and outside) your skin is exclusively in contact with the organic cotton,
  • The deep “fitted” and adjustable cut of the beanie allows you to cover your eyes while you sleep,
  • no irritating seams or annoying labels
  • available in 5 colors that are always soft and warm!


Its lightness gives it several possibilities and makes it a cap for all times: for the night, between 2 seasons or under another cap (wool…). It will also be appreciated by people who find it hard to bear “to have something on their head”.

Very attentive to the specific needs of chemically-sensitive people, we take care to use only biocompatible materials.

Be sure to carefully take your head size using the following diagram:

Protect yourself at night


Cleaning is quick and easy:

  • By hand, without rubbing or twisting

    • Leave to soak for a few minutes so that the fabric soaks in well
    • Use very little soap or non-aggressive laundry product (organic product type)
    • Squeeze the garment as you do for a sponge
    • NEVER RUB: in case of stain, use an old toothbrush, a little bit of soap (honey soap in organic stores) and rub gently
    • NEVER TWIST to wring out but squeeze gently
    • Dry flat or on a line, pinched regularly. Avoid full sun.
  • In washing machine

    • Place in a small laundry bag (as for underwears)
    • Use a non-aggressive laundry product (organic product type)
    • Maximum temperature 30°
    • Gentle spin in a full drum
    • Dry flat or on a line, pinched regularly. Avoid full sun.

    Grand mieux être

    Au delà du contact agréable, j’ai perçu instantanément un “mieux-être” par le sommet du crâne, comme la capuche d’un imperméable peut protéger d’une pluie glaciale.

    Je suis très satisfaite de ce bonnet, il est tout doux, léger et très agréable à porter et beau. On ne voit pas que c’est un bonnet avec des particularités, il passe partout. Je recommande cet article pour toutes les personnes qui sont sensibles (electrosensibles et peau délicate).
    Merci à toute l’équipe qui fait un beau travail de finition.

5G Protection

Our shields, and therefore our protective clothing against waves, have been designed from the start for protection over a wide spectrum of frequencies, covering the frequencies that are now those of 5G.

Protect against Waves Shield

The shield used is

  • 100% silver: silver is the best performing metal in terms of wave attenuation, which is why we do not use any other metal
  • Totally coated with silver (and non-woven with a metal thread), which explains its remarkable performance
  • Biocompatible (see Glossary)
  • Certified without nanoparticles
  • Tested to military standard ASTM D4935-10 and/or IEEE-STD-299-2006

The principle of attenuation of the electromagnetic wave is the principle of reflection. Grounding is therefore useless since it is only used to eliminate electrical surges and loss of charge as well as electrostatic discharges.

50 db attenuation

Thanks to the high percentage of silver used in its composition, the very high performance shielding of this article greatly reduces exposure:

  • high-frequency waves emitted by cordless DECT telephones, WLAN (wireless local area network) or Wifi wireless networks, mobile telephony, bluetooth, etc.
  • to the PLC of the Linky meter
  • to radiation from low frequency electric fields 50H

This shielding has an attenuation of 50 decibels; in other words, its efficiency is 99.999% against high and low frequencies, a reduction of 100,000 times the power of the wave (access to tests).
