Long-sleeved undershirt made of the new excellent cotton fabric Swiss Shield VENTUS for protection against mobile phone radiation such as transmission towers, WLAN, DECT phones, Bluetooth etc.
Now also available in navy blue.
Swiss Shield Ventus protects 99.975.% against the new WLAN and 5G and is particularly durable. Even after many washes, this fabric does not lose its protective effect.
These undershirts are cut extra large because the fabric is woven, so it is not stretchy. Thus, freedom of movement is still guaranteed.
