I like this tank top for several reasons. It's feels more comfortable wearing it compared to most other shielding fabrics which tend to be more metallic. This tank top has fabric that feels more like a natural fabric, like cotton, which it partly is. I first bought the medium, then later, I bought the large. I am usually a woman's size 6. I found the medium fits okay. The large seems a little big for me, but I wear it when relaxing at home. I gave it 4 stars, not five stars because I did not wash it yet because I was waiting for the recommended laundry soap I ordered to arrive. So I don't know yet how it will hold up to washing. But overall I like this tank top. I have sensitivity to EMR and I do notice wearing the tank top helps lessen symptoms I get from EMR exposure. I recently ordered my third tank top from this company. I wish they were in the U.S. instead of Canada and I wish they had affiliate marketing because I have been telling friends and family about this tank top. It would be nice to be able to earn something from recommending a good product. But one of the reasons I bought it was because it is made in Canada, not in China.
