I very much enjoy wearing this item, however, I feel it would be dishonest not to note that upon receipt of it, it was very obvious that there was either a different product displayed in the product photo above, or else due to reasons about which I could only speculate, the initial product was swapped out for a different build at some time in the past, and the information here has not since been updated. Still very comfortable, and an otherwise good product to my standards. I cannot attest affirmatively or negatively to it's EMF shielding capabilities. Perhaps there is simply not enough EMF radiation in my house to notice a difference. Going out and about, I have found brain fog to be less common in incidence, but that could also be due in part to cutting out certain foods from my diet at the same time as receipt of this item, so I will not comment upon that attribute of this product.
