The bottom of the DefenderShield Winter EMF Radiation Protection Beanie can be folded over to customize the length of the beanie, which can stretch to fit most heads. The EMF silver lining inside is anti-microbial and breathable, and the knit yarn outer will keep your head warm and cozy.
Use while near EMF-emitting devices, at night, or in locations where ambient EMF radiation coming from hot spots, WiFi routers, and/or cell phone towers is present.
For a thinner, more lightweight alternative (with child/newborn sizes), please see our Classic Beanie.
