The Signature Tinfoil Beanie

The one we wear. Hand-pleated from triple-ply aerospace-grade aluminum foil bonded to a breathable inner liner. Passive blocking across the active civilian RF band, plus 6G pre-emptive shielding at the crown.

Machine wash cold, do not bleach, do not tumble dry. Dents in the foil are not defects — they are calibration. Re-shape by hand as needed.

Fits most head sizes. Runs slightly loose by design — you want airflow under the shield to avoid heat buildup during extended wear sessions.
