Review on 🧢 DefenderShield Beanie: Cutting-Edge EMF Radiation Protection at Your Fingertips! by Richard Edwar

Nice cap, fits an average head well. I would guess it doesn't stretch well for a large head, but I haven't tested that theory. I'm only saying that because it's not as stretchy as some hats. However, it is very soft. If I put my phone in and close it for a minute, when I take it out it shows "no service" so I know it's blocking the waves.
