Wonderfully soft and comfortable beanie. The beanie has an intermediate layer of silver fabric which protects against microwave radiation. The inside and outside are made of wonderfully organic cotton and the beanie is soft and elastic.
The silver fabric is not treated or soaked with nanosilver (which can otherwise drop when washed and get into lakes & seas), but the fabric is made of pure silver. Tests are done and release a maximum of 5% after 20 washes.
