What is the Antiwave T-shirt for men?

It is a short-sleeved, round-neck T-shirt made in Germany from New Antiwave, a soft, stretchy knit of organic cotton and silver-coated polyamide that shields RF signals from cell towers, WiFi and cell phones.

What is the T-shirt made of?

89% organic cotton, 9% polyamide and 2% silver. The silver is a pure silver coating around the polyamide fiber, not nano silver. The organic cotton is from controlled organic cultivation (kbA).

How much shielding does it provide?

Up to 26 dB from 470 MHz to 960 MHz, 23 dB at 1800 to 1900 MHz, 21 dB at 2110 to 2170 MHz, 20 dB at 2.4 GHz WiFi, 17 dB at 3.4 to 3.7 GHz and 13 dB at 5 GHz WiFi. Every 10 dB is a tenfold reduction in signal power. These are maximum values, and shielding varies with the direction of the signal and how far the fabric is stretched.

Does it block WiFi and 5G?

It shields 2.4 GHz WiFi (20 dB), 5 GHz WiFi (13 dB), cell frequencies, and the 5G low band (26 dB at 700 to 750 MHz) and mid-band (17 dB at 3.4 to 3.7 GHz). Shielding is much lower at 20 GHz and above, so millimeter wave 5G is not covered.

Can I wash the T-shirt?

Yes. It is made to retain its shielding through about 40 washes. Wash gently on a delicate or wool cycle at 30 or 40°C (86 or 104°F), with no bleach and no detergents that contain bleach. Iron gently at a low temperature, and do not tumble dry or dry clean.

Can I wear it as underwear?

Yes. The T-shirt can be worn as an outer layer or as underwear.

Why does the label inside the shirt show a different size?

The shirts are made in Germany in European sizes, which run smaller than US sizes, so each size is named both ways. The label inside shows the EU size: a US Small has a label that says Medium, a US Medium says Large, a US Large says XL, a US XL says XXL and a US XXL says XXXL. The measurements in the size chart are those of the shirt you receive.

What size should I order?

Compare the measurements in the size chart in the Specifications tab with a T-shirt you already own and like, laid flat. If you are between sizes, speak to an expert before you buy.

How much does the T-shirt cost?

The Antiwave Organic Faraday T-Shirt for Men is $139.99.

Antiwave Organic Faraday T-Shirt for Men

This short-sleeved, round-neck T-shirt is made from New Antiwave, a right-left jacquard knit that combines combed organic cotton with silver-coated polyamide. It is soft, antistatic, elastic and has very good tear resistance. It is opaque, in a light grey with a silver shimmer, and can be worn as an outer layer or as underwear. The organic cotton is from controlled organic cultivation (kbA). Browse our full range of EMF clothing.

Shielding Performance

New Antiwave provides up to 26 dB of shielding from 470 MHz to 960 MHz, which covers TV broadcasting, 4G and the low 5G bands, and GSM and LTE. At higher frequencies shielding falls: 23 dB at 1800 to 1900 MHz, 21 dB at 2110 to 2170 MHz, 20 dB at 2.4 GHz WiFi, 17 dB at 3.4 to 3.7 GHz (5G mid-band) and 13 dB at 5 GHz WiFi. Decibels are a logarithmic scale: every 10 dB is a tenfold reduction in signal power, so 20 dB means 99% of the signal power at that frequency is blocked. These are the maximum values from the manufacturer's test report by the EMF Test Lab Bavaria, tested according to IEEE Std 299-2006. Shielding varies with the direction of the signal and how far the fabric is stretched, and it is much lower at 20 GHz and above, so millimeter wave 5G is not covered. See the Specifications tab for the full table.

Fabric

Composition: 89% organic cotton, 9% polyamide and 2% silver.
Silver: the polyamide fiber is coated all around with pure silver, not nano silver.
Weight and thickness: about 4.3 oz per square yard (145 g/m²) and about 0.02 inch (0.5 mm) thick.
Made in Germany.

Care and Washing

The fabric is made to retain its shielding through about 40 washes. Follow these care instructions:

Wash gently, on a delicate or wool cycle at 30 or 40°C (86 or 104°F).
Iron gently, at a low temperature (iron level 1).
No bleach, and no detergents that contain bleach.
Do not tumble dry.
No dry cleaning.

Sizing

These shirts are made in Germany in European sizes, which run smaller than US sizes. Each size is named both ways: for example, US Small (EU Medium). Choose the size you normally wear in US sizes, and check it against the measurements in the size chart in the Specifications tab. The label inside the shirt shows the EU size, so a US Small has a label that says Medium.

Size: US Small (EU Medium), US Medium (EU Large), US Large (EU XL), US XL (EU XXL, US XXL (EU 3XL)
