SYB Boxer Briefs


  • The World’s Most Protective Underwear: Our boxer briefs are a super simple way to block up to 99% EMF radiation from cell phones, laptops, wifi routers and other wireless devices from your body and reproductive organs.
  • 1 in 8 couples have trouble conceiving and multiple scientific studies have linked cell phone radiation with up to a 40% decrease in quantity and quality of sperm; the World Health Organization lists cell phone radiation as a Class 2B carcinogen. Even cell phone companies like Apple warn you not to keep your phone in your pocket, because radiation exposure can exceed FCC regulations.
  • Don’t be fooled by EMF pendants or charms that claim to harmonize or neutralize EMF radiation without any scientific proof. Our boxer briefs use universally-accepted and scientifically verified principles to shield your body from EMF radiation. Woven into the cotton is a mesh of silver microfibers that form a shield to block EMF radiation, to provide powerful EMF protection.
  • Delicate or hand wash with cold water. Air dry. Do not bleach, iron, or dry clean. Soft, odor killing, ultra comfortable, stretchable. Toxin-free and hypoallergenic.

Our high-quality boxer briefs protect your body and do not interfere with your cell phone reception or battery life. These boxer briefs are cotton, woven with silver microfibers that form a powerful shield to deflect cell phone radiation away from your body and reproductive organs.

In addition, these light-weight, machine-washable, stretchable and super comfortable boxer briefs feature advanced temperature regulation and anti-odor technology prevents the growth of odor-causing microbes.

Shield Your Body from harmful EMF radiation with our SYB Boxer Briefs.

PLEASE NOTE: Our boys sizes are branded ‘Riparo’, and our men’s sizes are branded ‘SYB’. This is because in 2016, SYB purchased Riparo’s complete inventory of smaller sizes, and in 2017 we began manufacturing our own SYB-branded boxers from the same design, and we began by producing the mens medium, large and extra large sizes.
