A raw silver shielding textile for controlled prototypes, interiors, and builds.
Waitlist access
Prototype format: textile dimensions and finishing confirmed at bulk production.
- S05 textile system with 40-50 dB (declared material value).
- Silver textile construction selected for the intended use case.
- Pre-launch candidate pending independent EU lab testing before preorder opening.
A flexible silver-blend textile supplied by the meter for softer apparel and specialty shielding applications.
Every pre-launch Zanthera product keeps material performance, garment coverage, and final lab verification separate so the product page stays useful without overstating real-world exposure reduction.

Attenuation
Frequency response by signal family.
| Signal family | Frequency | Attenuation |
|---|---|---|
| GSM / 3G / 4G | 0.9 - 1.9 GHz | 40-50 dB (declared material value) |
| Wi-Fi | 2.4 GHz | 40-50 dB (declared material value) |
| Wi-Fi 5 GHz / 5G Sub-6 | 5 GHz / Sub-6 | 40-50 dB (declared material value) |
Declared material specs. Pending final independent EU lab testing.
EN: This product is not personal protective equipment (PPE) and has no medical properties. Attenuation values refer to the shielding fabric measured under laboratory conditions; actual exposure reduction depends on garment coverage and fit.
SV: Produkten är inte personlig skyddsutrustning och har inga medicinska egenskaper. Angivna dämpningsvärden avser tyget under laboratorieförhållanden; faktisk exponeringsminskning beror på plaggets täckning och passform.
02
Cut, layer, test.
Shielding performance depends on the continuity of the textile and the area it covers. We keep the data tied to the material so each build can be evaluated on its own construction.
