EMF shielding clothing: materials guide

EMF shielding clothing: the science in the fibres

Suitable conductive textiles use connected conductive fibres or coatings to interact with radiofrequency energy. Some energy is reflected and some is absorbed, reducing the amount transmitted through the material. This physical reduction is called attenuation.

Silver and other conductive materials can be incorporated into textile structures. The resulting performance depends on frequency, conductivity, fabric construction and the way the material is measured. For clothing, seams, openings and coverage also matter.

Read the option label first

A single style can be offered in several material versions. Choose the complete combination of colour, material and size, then check the details for that specific product.

For example, the AJ501 vest lists these supplier-declared compositions for its specified fabric:

MTF: 41.8% cotton, 32.1% polyester fibre and 26.1% metal fibre.
50Ag: 50.6% polyester fibre and 49.4% silver fibre.
75Ag: 25.2% polyester fibre and 74.8% silver fibre.
100Ag: 100% silver fibre.

These figures describe the supplier-stated composition of the specified fabric. The option names identify material versions; a shielding report measures their performance under stated conditions. Check the exact product details because compositions and garment layers vary between styles.

EMF protection clothing: what should you look for?

When comparing EMF protection clothing, look for evidence that matches the exact fabric or garment you want. A useful shielding report should identify:

The material or finished garment tested, including its version.
The laboratory, date and test method.
The frequency range and results across that range.
The test arrangement and the condition of the sample.

Match the report to the exact material or garment you are comparing. The sample identification and frequency range help you understand which result applies to your chosen option.

From conductive fabric to a garment you wear

A fabric result is a useful starting point. Garment construction adds another layer of detail: the shape, seams, openings and position of the source can change the measured result. Compare coverage and construction alongside the fabric when choosing EMF shielding clothing.

RF attenuation describes a physical effect. Claims about sleep, fertility or other health outcomes require separate evidence.

Find the right EMF clothing for your routine

Start with the layer you need: a sleeveless vest leaves your arms free, while jackets and longline coats offer different sleeve and hem lengths. Compare measurements, pocket layouts and fastenings, then choose the available material version for that style.
