(I wrote my longer review in the silver stretch doo rag bandanna section, just fyi). Long story short, after 5G was rolled out in the atmosphere of my apt bldg (replacing I guess 4g? for the public wifi hotspots), I suddenly started experiencing inexplicable deep all day brain fog, and fatigue, and heat radiation to my face and head. ALso my immune system got very low / weak, and I developed a flu without any "classic" flu symptoms. IN a nutshell, what ended up helping me the most impressively, was two products used in combination: This face veil, used in combination with wrapping my head up in their silver stretch bandanna doo rag product. First I wrap my head in the silver stretch bandanna doo rag, and then I placed this face veil over my head, so that essentially I had a complete faraday cage around my head, from my head to face down to neck. This combination is what gave me huge relief , in terms of my head. The hats (baseball cap and safari hat) didnt work as well as this combination. Now, I sleep with that combination on my head, until I can invest in getting one of the silver material bed canopies. So any of you guys out there having severe disturbance to your head/ face, from the 5G rollout, try this combination. I have found this veil to be definitely blocking / protective, but I would say use in combination together with the silver stretch doo rag, to make a complete faraday cage around your head. ALso, the hoodies and silver pants seem effective to me as well, and they are comfortable to wear. The pants are like spandex feeling, and the hoodie is just soft casual feeling material.
