Boiled wool anti-wave hats.

Need protection and warmth?

Our woolen hat “A winter in Berlin” will delight you!

Elegance in protection from Ondes et Protection ®.



Why a boiled wool anti-wave hat?

To tackle winter while protecting yourself against the waves with a warm and elegant hat.

60 dB protection thanks to the 20% silver used in the shielding composition.

How did we design it?

  • Shield composition: 80% spandex, 20% silver.
  • Composition of the organic fabric: 95% GOTS certified cotton, 5% spandex
  • Tri-layer construction: a layer of protective fabric sandwiched between a layer of GOTS certified organic cotton and a layer of boiled wool (inside and outside): your skin is exclusively in contact with the organic cotton,
  • The cut of the hat covers the head well and thus ensures maximum and comfortable protection,
  • Increased comfort: no seams, no irritating labels,

Depending on your needs and desire, you can wear it without a fold, thus deepening the hood, or with a fold, surrounding your face without forgetting to protect it.

The hat’s tie panels will surround your face or be tied at the back of your head

A hat that never ceases to amaze you!

As with all our products, our hat is made in France.

L’entretien est facile
 et rapide:

  • A la main, sans frotter ni tordre

    • Laisser tremper quelques minutes pour que le tissu s’imbibe correctement
    • Utiliser très peu de savon ou de produit de lessive non agressif (type produit bio)
    • Presser le vêtement comme on le fait pour une éponge ou un lainage
    • NE JAMAIS FROTTER: en cas de tache, utiliser une brosse à dent souple, un petit peu de savon (savon au fiel en magasin bio) et frotter délicatement
    • NE JAMAIS TORDRE pour essorer mais presser délicatement
    • Sécher à plat ou sur une corde, pincé régulièrement. Eviter le plein soleil.
  • En machine

    • Placer dans un petit sac de lavage (comme pour la lingerie)
    • Utiliser un produit de lessive non agressif( type produit bio)
    • Température maxi 30°
    • Essorage délicat dans un tambour plein
    • Sécher à plat ou sur une corde, pincé régulièrement. Eviter le plein soleil.

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 uselesssince it is only used to eliminate overvoltages and losses of electrical charges as well as electrostatic discharges.

60 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 electric current linky
  • to radiation from low frequency electric fields 50H

This shielding has an attenuation of 60 decibels; in other words, its efficiency is 99.9999% against high and low frequencies, a reduction of 1,000,000 times the power of the wave (access to tests).
