OVERVIEW – RadiArmor’s unisex RF blocking hat features a breathable liner made of woven silver fibers that blocks over 99% of high frequency RF and millimeter wave radiation commonly associated with WiFi, cellular and 5G communication.

LAB VERIFIED – Breathable woven silver fabric is lined throughout the perimeter of the hat and is third party verified to block 99.9% of high frequency RF. Average reduction to the head inside the hat exceeds 90%. NOTE: This hat protects your head, not your whole body. Only a faraday cage can block RF from your whole body. When testing using an RF reader, please measure inside the hat. See testing instructions below.

INTEGRITY: Many RF protection products claim 99% reduction but are referring only to the radiation blocking material itself, NOT the protection you receive. Wearing a pendant that blocks RF offers as much a protection as a waterproof pendant would protect you in the rain. At RadiArmor, we only make RF protection products that provide real protection.

SIZING – This unisex hat features an adjustable strap and is designed to fit most size heads. May not be suitable for size XL. Please see size chart.

CARE – Silver is naturally odor resistant and rarely requires washing. If necessary, hand wash and hang dry only. Silver naturally changes color over time but this does not effect the RF shielding capabilities.
