Listening to your brother's self-righteous girlfriend talk is even less pleasant than hearing fingers on a chalkboard. Every time she comes over, this paranoid prima donna lectures you about the dangers of "wireless waves," then makes you unplug the router and turn off your smartphone.
You'd like to buy her a plastic bubble to live in, but instead go for the Silverell Hoodie, which tested to 90 percent or better RF attenuation over the frequency range from 20-MHz to 8-GHz. Plus, it has antistatic behavior, minimizes body odor (great if she's also afraid of showers) and it has an inhibitory effect on the growth of bacteria. Talk about a multipurpose product!
