EMF Protection & EMI Shielding Anti-Radiation Silver Fiber Underwear - Long Leg Base Layer for Men & Women | Perfect for Daily Wear, Work & Travel

I tested this with my cel phone's meter ( cel phones have a very accurate digital EMF meter, not the bar graph. It tells on web how to access it for your particular phone ) and it blocked the EMFs very well. Actually the proper term is "attenuate" since no material will block 100%. >>> you have to get 2-3 sizes larger than your normal size. I take a large-XL and this is 3XL. If you normally take a XL or larger, this might not be the right EMF pants for you. The legs are thin and stretch to fit. My first order was a 2XL, and it's a snug fit. I almost returned it, but kept it and it's barely ok.
