EMF Winter Beanie (S04/S01)
Waitlist access
Colour: silver grey
Size
Prototype fit: close technical fit. Final grading confirmed at bulk production.
A soft winter beanie engineered with silver-based shielding textiles for everyday cold-weather coverage.
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.

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.
01
The S04 system uses silver-based fibers to create a shielding textile surface. The goal is straightforward: measurable attenuation in the covered area, with comfort details handled by the garment construction.
02
Every pre-launch candidate keeps declared material values separate from final independent EU lab testing. EU lab confirmation is the gate before preorder access opens.
