Light Knit Cap Outdoors

OVERVIEW

Available in 3 colors, RadiArmor’s unisex EMF blocking knit cap features a breathable liner made of pure silver woven fibers that blocks over 99% of high frequency RF and millimeter wave radiation commonly associated with WiFi, cellular and 5G communication. Also blocks 99% of electric fields measured in V/m. Average reduction to the head inside the hat exceeds 90%. NOTE: Does not block low frequency magnetic fields measured in milligaus (mG).

SIZING AND CARE

The outer material is made of plush core spun yarn that is warm, breathable and stretches to accommodate any size head.

The liner is made of real silver, which is naturally anti-bacterial and odor resistant, so you rarely need to wash it.  If necessary, hand wash and hang dry only. Silver naturally changes color over time but this does not effect the EMF shielding capabilities.

TESTING YOUR HAT

First, make sure you that you are using an EMF reader that measures high-frequency RF or microwave radiation. This is the kind of EMF emitted by cell phone towers, WiFi, and 5G. This is also the type of EMF most commonly associated with potential health risks according to studies. For best results, find a cellphone or 5G tower and compare background levels to levels inside the hat. Many readers are based on a logarithmic scale, so we also recommend a reader that registers real numbers.
