Description
EMF Shielding in a Cap You Can Wear Every Day
Cell towers, WiFi routers, Bluetooth devices, and 5G infrastructure broadcast wireless RF radiation from every direction. Your head and brain is exposed to these ambient signals during commutes, at the office, while walking outdoors, and in public spaces. A standard baseball cap shades your face. This one shades your face and shields your head from wireless radiation.
The DefenderShield® EMF Radiation Protection Baseball Cap is lined with a silver shielding interior fabric that blocks up to 99% of wireless RF radiation from 10 KHz - 40 GHz - covering WiFi, Bluetooth, cellular signals, and low- to mid-band 5G frequencies. The VELCRO back strap has no opening - the shielding coverage wraps continuously around the crown of your head from front to back with no gap for radiation to pass through.
A Performance Cap That Blocks RF and UV
The outer shell is 90% Nylon / 10% Spandex - lightweight, breathable, and performance-ready. The structured mid-profile design sits comfortably on a wide range of head shapes. The brim provides UV protection, helping shield your scalp and face from sun exposure during outdoor use.
The silver shielding interior is naturally antimicrobial, resisting odor and bacteria buildup during extended wear. The adjustable VELCRO strap fits head circumferences up to 23.5 inches. Available in Black.
Key Features
The interior of the cap is lined with silver shielding fabric that blocks up to 99% of wireless RF radiation from WiFi, Bluetooth, cellular, and low- to mid-band 5G. The shielding covers the entire crown of the cap, from front to back.
The VELCRO back strap allows you to adjust the size without a gap or opening. Unlike standard baseball caps with a cutout or hole in the back, this cap provides continuous shielding across the entire crown. No gap means no unshielded path for RF radiation to reach the back of your head.
The silver shielding interior is naturally antimicrobial. It resists odor and bacteria buildup during extended daily wear, reducing the need for frequent washing.
The back strap adjusts to fit head circumferences up to 23.5 inches. The VELCRO closure is quick to adjust and holds securely throughout the day.
How to Use
Wearing the Cap
1. Put the cap on like a regular baseball cap. The silver shielding interior covers the entire inside of the cap.
2. Adjust the VELCRO strap for a snug fit. A secure fit ensures the shielding stays in full contact with the crown of your head.
3. Wear it in any environment. Commuting, outdoor activities, office, travel, or any setting with ambient wireless signals.
What the Cap Covers and What It Does Not
• Covered: crown of the head (top and sides), with continuous shielding from front to back (no back opening). The brim provides UV protection.
• Not covered: face, ears, and neck. For neck and upper-body coverage, pair with the EMF Protection Wrap Scarf. For full-head winter coverage, switch to the EMF Protection Winter Beanie.
Care Instructions
• Hand wash cold with gentle detergent. Air dry.
• Do not bleach, machine wash, or tumble dry.
• The antimicrobial silver lining reduces odor - frequent washing is not necessary.
• Gentle care preserves the shielding integrity of the silver interior.
