Product Overview The Mission Darkness EMF Blackout Hat is a shielded baseball-style cap built for everyday wear. It is lined with a discreet layer of TitanRF™ Flex Faraday Fabric — a nickel and copper composition lab tested and certified to IEEE 299-2006 — providing a barrier between your head and high-frequency electromagnetic radiation from cell towers, smart meters, Wi-Fi access points and other sources. The hat is breathable, flexible and uses an adjustable snapback closure that fits most adult head sizes from 21.5" to 23.6" (55–60 cm) circumference. A small Faraday testing pouch constructed from the same TitanRF™ Flex Fabric is included so the shielding can be verified using the Mission Darkness app. The hat ships in a deluxe resealable box.
