Good to know
  The beanie shields the top and sides of your head from ambient wireless RF radiation. It does not cover the face, ears fully (depending on fit), or neck. The shielding works while the beanie is on your head - no setup, no charging. For neck and upper-body coverage, pair with the EMF Protection Wrap Scarf. This is a different shielding technology than the Ultra Armor® used in DefenderShield’s device cases.
Description

A Winter Hat That Shields Your Head from the Wireless Signals Around You

Cell towers, WiFi routers, Bluetooth devices, and 5G infrastructure broadcast wireless RF radiation in every direction, continuously. When you walk through a city, sit in a café, ride public transport, or work in an office, your head is exposed to these ambient signals from every angle. A standard winter hat keeps you warm. This one keeps you warm and shielded.

The DefenderShield® EMF Radiation Protection Winter Beanie is lined with a silver-threaded shielding fabric (42% Silver / 53% Polyester / 5% Nylon) that blocks up to 99% of ambient wireless RF radiation from reaching your head. The shielding is independently tested. The outer shell is a soft cotton-acrylic blend (60% Cotton / 40% Acrylic) that insulates against cold weather and feels like a standard winter beanie.

Looks Like a Regular Beanie, Works Like a Shielding Layer

The beanie is a stretchy pull-on design that fits most adult head sizes (18–26” circumference). The fit is unisex - snug enough to stay in place, loose enough for all-day comfort. At 2.1 oz (approximately 60 g), it adds no noticeable weight or bulk. The silver-threaded liner is discreet and invisible from the outside.

Wear it during commutes, outdoor activities, travel, indoor work near wireless devices, or while sleeping in rooms with WiFi routers or smart home infrastructure. For complete head coverage including the face and neck, layer with the EMF Protection Wrap Scarf or the EMF Protection Sleep Mask.

Key Features
🛡️ Silver-Threaded Shielding Liner - Up to 99% RF Blocking
The inner liner uses silver-threaded polyester fabric (42% Silver / 53% Polyester / 5% Nylon) to block up to 99% of ambient wireless RF radiation. The shielding covers the top and sides of your head when the beanie is on. Independently tested for shielding performance. ❄️ Warm Cotton-Acrylic Outer Shell
The outer layer is a 60% Cotton / 40% Acrylic blend that provides reliable insulation for cold weather. Soft, breathable, and warm - the beanie performs as winter headwear first, with the shielding built invisibly inside. 🧢 Stretchy Pull-On Fit - One Size, Most Heads
The stretchable knit fits head circumferences from 18 to 26 inches. Unisex design, snug but comfortable. No buttons, clasps, or adjustments - pull it on and go. 🪶 Lightweight and Discreet - 2.1 oz
The silver-threaded liner adds no perceptible bulk or weight to the beanie. At 2.1 oz (approximately 60 g), it looks and feels like a standard winter hat. The shielding is invisible from the outside. 😴 Wearable Day and Night - Including Sleep
Wear the beanie outdoors, during commutes, while traveling, or in bed. If you sleep in a room with WiFi routers, smart meters, or Bluetooth devices, the beanie reduces the ambient RF reaching the top of your head throughout the night. 🧵 Dual-Layer Construction
The beanie combines two functional layers: the cotton-acrylic outer for warmth and style, and the silver-threaded polyester inner for RF shielding. Both layers work together without adding stiffness or discomfort.
How to use

Wearing the Beanie

1. Pull the beanie on like a regular hat. Ensure the shielding liner covers the top and sides of your head.

2. Pull it down far enough to cover your ears (or as far as your preferred fit allows). The more surface area the beanie covers, the more RF radiation it shields.

3. Wear it in any environment. Outdoors, indoors, during commutes, travel, work, sleep, or any situation where ambient wireless signals are present.


What the Beanie Covers and What It Does Not

• Covered: top and sides of the head (and ears, depending on how far down you pull the beanie).

• Not covered: face, neck, and any area below the beanie’s hem. For eye coverage, pair with the EMF Protection Sleep Mask. For neck and upper-body coverage, add the EMF Protection Wrap Scarf.


Care Instructions

• Hand wash cold with gentle detergent.

• Air dry only.

• Do not bleach, iron, or machine wash.

• Gentle care preserves the shielding integrity of the silver-threaded liner.

Very good but I would hope you could use cotton or wool for the actual beanie.

FREQUENTLY ASKED QUESTIONS

EMF Radiation Protection Winter Beanie FAQ

Ambient wireless RF radiation from the environment around you. Cell towers, WiFi routers, Bluetooth devices, and 5G infrastructure broadcast RF signals continuously. The silver-threaded liner blocks up to 99% of this radiation from reaching the top and sides of your head while the beanie is on.

The top and sides - and ears, depending on how far down you pull it. The beanie does not cover the face or neck. For eye coverage during sleep, pair with the EMF Protection Sleep Mask. For neck and upper-body coverage, add the EMF Protection Wrap Scarf.

No - this uses silver-threaded polyester designed for wearable comfort. DefenderShield device cases use Ultra Armor or Ultra Armor+®, which are rigid composites optimized for blocking radiation from a single device. The beanie uses a silver-threaded polyester liner woven into a soft, stretchy knit for all-day head coverage. Both block wireless RF radiation; the materials and applications are different.

Yes - the beanie is lightweight and soft enough for overnight wear. If you sleep in a room with WiFi routers, smart meters, or Bluetooth devices, wearing the beanie reduces the ambient RF reaching your head throughout the night. At 2.1 oz, it adds negligible weight. Pair with the Sleep Mask for combined head + eye shielding during sleep.

The beanie is standalone headwear. The jacket hood requires wearing the full jacket. The DefenderShield Hooded Jacket includes a shielded hood, but you need the entire jacket on to use it. The beanie gives you head shielding without putting on a jacket - useful indoors, in warm weather, during sleep, or when you want head coverage without full outerwear.

Most likely - the stretchy knit fits head circumferences from 18 to 26 inches. The pull-on design conforms to a wide range of head sizes and shapes. The fit is snug but comfortable, and the material does not lose its stretch over time with proper care.

Hand wash cold with gentle detergent. Air dry only. Do not bleach, iron, or machine wash. These methods can damage the silver-threaded shielding liner. Gentle care preserves both the shielding performance and the softness of the outer shell.

No - the beanie looks like a standard winter hat. The silver-threaded shielding is the inner liner, completely hidden by the cotton-acrylic outer shell. From the outside, it is indistinguishable from a regular beanie.
