1. 100% Cotton.

2. OVERVIEW  – The EMF blocking hat features a breathable liner made of knitted silver fibers that blocks over 99% of high frequency RF and millimeter wave radiation commonly associated with WiFi, cellular and 5G communication.

3. REAL PROTECTION – EMF shielding liner exceeds 99% reduction of high frequency RF and millimeter wave frequencies and is lined throughout the inside of the entire hat. Average reduction to the head inside the hat exceeds 90%.

4. INTEGRITY – Many EMF protection products claim 99% reduction but are referring only to the radiation blocking material itself, NOT the protection you receive.  At Huntoo, we only make EMF protection products that provide real protection.

5. SIZING – This unisex hat features an adjustable strap to fit most people with the size of 58 cm circumference. 

6. NATURALLY ANTI-BACTERIAL – Silver is naturally anti-bacterial and odor resistant, so you never need to wash it. The outer material is pure cotton. If necessary, hand wash and hang dry only. Silver naturally changes color over time but this does not effect the EMF shielding capabilities.
