Good to know
This blanket reduces the EMF radiation reaching your body — it is not a sealed Faraday cage and does not block signals completely. Your devices stay connected and functional while you are covered. Think of it like an umbrella: it significantly lessens the amount of radiation reaching you, without cutting off your connectivity. The shielding works best when the blanket is positioned between your body and the device or EMF source. For easier care, add on the optional duvet cover — it is machine washable and does not interfere with the blanket's shielding.
Description

Block Emissions, Stay Connected — Multi-Layer EMF Shielding for Everyday Use

Every time you use a laptop on your lap, sit at your office desk, scroll on your phone in bed, or sit near a WiFi router, your body is absorbing wireless EMF radiation from Radio, 2G-5G cellular, Bluetooth, and WiFi. 

The DefenderShield EMF Protection & Anti-Radiation Blanket is a premium, scientifically engineered metallic fabric barrier that helps reduce exposure to electromagnetic radiation from nearby wireless devices and surrounding environments, using two layers of advanced shielding fabric sewn inside a soft bamboo viscose and cotton exterior. It is designed for both comfort and performance, making it an excellent choice during pregnancy, for newborns, or as a daily protective layer against EMFs.

Good to know: your devices stay fully connected and functional while you are covered. 

This is not a Faraday bag. It’s not meant to cover your device, but instead cover your body to protect you from device emissions. The blanket uses a floating ground design that reduces and dissipates wireless EMF before it reaches your body — blocking up to 99% of wireless radiation from 300 Hz to 10 GHz, which covers Radio, 2G through 4G cellular, Bluetooth, WiFi (2.4 GHz and 5 GHz), and 5G low and mid-band. Think of it as an umbrella: it substantially reduces what reaches you, without cutting off the connection.

Great for Babies and Adults with Delicate Skin.

The exterior is a 70% bamboo viscose, 30% cotton blend — naturally breathable, soft against sensitive skin, and free from heavy chemical finishes. The materials are hypoallergenic for daily contact. The EMF shielding extends into the built-in hood, allowing you to swaddle and protect newborns and infants. Recommended as a swaddle from birth until rolling. For loose blanket use, wait until 12–18 months to ensure a safe sleep environment.  .

Whether you need compact personal coverage or broader protection for rest and sleep, there’s a size for every use case:

  • Small (36" × 35") — best for lap coverage, infant swaddling, children, and travel

  • Throw (45" × 60") — a flexible everyday option for home, lounging, work, or travel

  • Medium (75" × 53") — sized for full single-person coverage during work, lounging, or sleep. Fits the top of a full mattress with no overhang.

  • Large (80" × 60") — offers more spacious individual coverage or comfortable shared use. Fits the top of a queen mattress with no overhang.

  • X-Large (84" × 75") — covers the top of a king mattress without wrapping the sides

We've opted for a unique size that covers the top of your mattress rather than a traditional bed size. This targets the areas of your body most vulnerable to EMF radiation during sleep and allows us to offer a focused, more affordable product. While it may not fully drape over the sides of your bed, it prioritizes protection and value

For everyday care, add the optional made-to-fit washable duvet cover, which protects the blanket from stains and wear without affecting the shielding underneath.

For complete protection, pair this blanket with DefenderShield other EMF Shielding Clothing, or Laptop EMF Shields and RFID Blocking Phone Cases that also block Extremely Low Frequency (ELF) radiation, for a comprehensive defense against daily EMF exposure.

Key Features
🛡️

Advanced Wireless Multi-Layer EMF Shielding — Up to 99% Reduction

Two layers of advanced wireless shielding fabric are sewn inside the blanket, blocking up to 99% of wireless EMF radiation from reaching your body. The shielding covers the full relevant radio frequency spectrum: Radio, 2G-4G cellular, 5G Low-Band, Bluetooth, WiFi, and 5G Mid-Band (300 Hz to 10 GHz). Your devices stay fully connected — only the radiation reaching your body is reduced.

 📡

Block Emissions, Stay Connected

Unlike a sealed Faraday bag, this blanket is designed for active use with connected devices. Use your phone, work on your laptop, and stay on WiFi — the shielding reduces the radiation passing through the blanket to your body while all your devices continue to function normally. This makes it practical for daily work, school, travel, and rest.

 🌿

Hypoallergenic, Sustainable Bamboo & Cotton Exterior

Our signature blend of 70% Bamboo Viscose and 30% Cotton was chosen for its incredible softness and breathability. We’ve skipped the heavy chemical finishes to ensure a fabric that is gentle against the most sensitive skin—from newborns to adults. Our Eco-safe and sustainable materials are designed for long-term daily contact with the whole family.

 👶

EMF Shielding Built Into the Hood — Swaddles & Protects Little Ones

The built-in hood carries the same multi-layer EMF shielding as the body of the blanket. It is designed to swaddle and protect infants and young children, allowing you to wrap them securely while shielding their heads and bodies from wireless emissions during rest, feeding, and quiet time.

 🧺

Made-to-Fit Washable Duvet Cover (Optional Add-On)

The optional duvet cover is a 100% sateen cotton, machine-washable outer layer that fits perfectly over all four blanket sizes. It protects the blanket's shielding layer from stains and frequent washing — extending the life of the shielding fabric. The duvet cover does not interfere with the blanket's EMF shielding effectiveness. Available in Gray, Taupe, Sage Green, Pink, and Blue, in select sizes.

 📐

Available in 5 Sizes — Individual to Full-Bed Coverage

Designed to suit a wide range of routines, these five size options make it easy to choose the level of coverage that fits your day. Compact sizes are ideal for travel and targeted personal use, mid-range options provide full individual coverage for work or sleep, and the largest size is made to cover the top of a king mattress (our blankets are sized to cover the top of the mattress with no overhang to reduce both the weight and cost).

 

    How to Use

    Getting the Most from Your EMF Blanket


    1. Position the blanket between your body and the EMF source. The shielding works directionally — place it over your lap when using a laptop, over your torso when using a phone in bed, or over your body when near a WiFi router. The blanket reduces radiation from getting to the other side; it does not create a sealed enclosure around you.
    2. Use for work with a laptop. Drape the blanket across your lap, torso, and legs with the device on top — this positions the shielding between the laptop's underside (a major EMF emission point) and your body. You can continue working normally: WiFi, video calls, and all connections remain active. We recommend using a hard-sided DefenderShield laptop shield to offer ELF protection as well.
    3. Use during sleep or rest. Pull the blanket over your body while sleeping near a phone, router, or other wireless device. The Medium size covers the top surface of a full bed, the Large covers the top of a queen bed, and the X-Large size covers the full top surface of a king mattress for whole-body protection during sleep.
    4. Use the hood to swaddle infants and babies. The built-in hood carries full EMF shielding. Wrap the blanket around your baby with the hood over their head for protected swaddling during quiet time. Do not use it as a blanket for your child unsupervised until 18 months old.
    5. Travel use. The blanket is a practical travel companion — use it on planes where WiFi and device emissions are close and constant, in hotel rooms near routers, or any environment where you want a simple, portable layer of protection.


    Care Instructions — Protecting the Shielding Layer

    • Recommended: use the optional duvet cover — machine washable, protects the blanket from stains, and reduces the frequency of hand washing needed.
    • Hand wash only (without duvet cover): use cold, soapy water with mild detergent or specialized metallic fabric cleaner. Be gentle.
    • Air dry only — do not place the blanket in a dryer. Hang to dry completely before use.
    • Do not bleach, iron, or dry clean — these can damage the metallic shielding fibers and reduce effectiveness.
    • Machine washing and tumble drying will degrade the shielding material over time and are not covered under warranty.

    make sure you uncheck onward bound safe delivery fee. 60 extra dollars, wow

    love the blanket, was not impressed how onward bound charged me for a safe delivery fee, i would think that defender shield would assure that the product would be delivered, when ordering if I do next time, will make sure there are NO hidden cost, I think paying 700.00 for a blanket would be enough to satisfy the company, and have it delivered to me with out the additional cost,

    We're so glad to hear you love your blanket!

    We also want to address your feedback regarding the Onward shipping protection. We understand why that charge might have been a surprise.

    To clarify, Onward is an optional, third-party shipping insurance service that we offer. It's designed to protect your package against loss, theft, or damage during transit, and it also allows for free returns if needed. While we always work diligently to ensure smooth delivery, Onward provides an extra layer of security directly to you for added peace of mind.

    We sincerely apologize if the option to decline this service wasn't as clear as it should have been during your checkout. We strive to make all costs transparent and provide several opportunities to remove DefenderShield Checkout+ (our name for the Onward service) before completing your purchase. We're always looking for ways to improve this transparency.

    XL blanket does not fit a king size bed

    I’m very grateful to have this blanket to protect hubby & i while we are sleeping. It is very soft and a nice weight - not too light & not too heavy, so, hopefully, i can use it year round, since we have the four seasons here. I was a bit disappointed that the XL blanket does not a fit a king size bed, even though I inquired if it would prior to purchasing it. I don’t have a cali king; just a regular king. It needs to be much more generously sized on the sides, as there is no overhang, whatsoever! Still happy i bought it, just wish for the price, it had overhang on the sides…if it did, I would have definitely given it 5 starts. Also, i wish it was machine washable, as the duvet cover does not work at all. The duvet cover only has 1 tie on each side inside,, so the blanket bunches up into the middle of the duvet, thus not adequately protecting our bodies. If the duvet had 3 ties on each side, it would work much better at keeping the blanket in its proper place. Do not get the duvet cover until that defect is fixed!

    Unfortunately, Some regrets…

    I bought my large size blanket June of 2023. I made this purchase because I was having to spend time somewhere that there were 5G posts popping up everywhere.

    I’ve given my review 4 stars as I do believe it does what it is intended to do. But here’s what I am unhappy about…

    No fault of Defender Shield, but I have problems sleeping at night. I move much more than the average person. What I disliked immensely about this blanket was that it had no stitching from end to end that would hold the inside in place. I felt like I was moving around with a large deflated balloon on me, which made for waking up EVEN MORE than I usually do.

    For those who do not own the blanket, It is hard to describe what happens when you move the blanket around. Best I can say is that there’s a top and bottom layer. In between, there is the protective material (presumably Silver fibers) and AIR. Well, these two layers, top and bottom, come apart and, when they do, you have one big mess of a heavy blanket, moving around with you, but not really structured to stay over you like a blanket.

    Please understand, I confessed I have issues with sleeping. The average person probably won’t experience this annoyance as they won’t move around, or kick around, very much. But for me, I found myself wrestling with this blanket, and it was so very annoying and even more disturbing to an already sensitive sleep pattern.

    I really wanted to give it a 3-star rating but, because part of the problem is me, I did not. Still, why can’t a few stitches be added, here and there, through the length of the blanket, kind of like a quilt, to hold the two layers together??? Even two or three stitches would have helped.

    This was a big sacrifice purchase for me. I am actually homeless, after losing my spouse 3 years ago, and rely on the mercy of a friend until I can find my way to renting my own personal home again. I don’t mention this because I need a pity party, but because I just want to inject some “reality of life” into this. I put over $400 into this blanket, that’s $400 less I had for other needs. If I could have returned it, I would have, but I couldn’t due to my circumstances.

    Overall, I would rate it a “decent” purchase, but definitely not a “great” one, at least not in my case, if I am to be honest. I’m 66 y.o. and could have used my very limited income on more practical needs.

    A couple of stitches to pin together top and bottom of my blanket would have made a huge difference.

    Thanks for reading.

    Oh My God!! Wonderful blanket!!

    I have to admit I was skeptical because I own a lot of different EMF protection that is just ok. I ordered the medium size blanket and just received it yesterday. I decided to wrap myself in it when I went to bed last night and as I was lying there I could feel my whole body somehow let go and relax at a deeper level. Honestly I was shocked. I had a great night sleep and even slept later than usual. I immediately came back to the site this morning to order the scarf which I will use when I travel and hang out in front of the TV. I may even try taking the blanket with me to Greece in Sept! Thank you Defender Shield for making superior products!!

    I have emf hoodies,shorts, hats, scarves, gators sleeping bag, gloves, socks and more.

    The small defender blanket here is my favorite of all. The blanket is so soft and cozy and very well made. Love the bamboo material. It is weighty as well, which adds to the comfort. I use it for different purposes as it finally wraps itself around my neck and head at bedtime to protect me from the nightly emf exposures. Someday I will step up to the next size. I would definitely recommend this for babies.

    Love it!

    My iPad left a red burn mark on my leg one day when I was using it sitting in my lap which prompted me to buy this blanket. No more burnt legs! I love that I can fully open the blanket and have it cover my entire body, or fold it into a small square and use it only in my lap. Very versatile! Also I thought it would be quite hot underneath it but it's actually quite cooling! I recommend getting the accompanying blanket cover, especially if you have kids or pets. Love love love my new blanket and cover!! Worth every penny!

    Regret spending so much money on it.

    The blanket works like an umbrella. It means that when you are looking at your screen, your head, and especially your eyes, get exposed even more than when you don't use the blanket. When this was mentioned on the website, no one would buy the blanket anymore.

    Sending back is not really an option because I live abroad and the postage for shipping will be too high.

    Hello Marianne,

    FREQUENTLY ASKED QUESTIONS

    EMF Protection Anti-Radiation Blanket FAQ

    Genuine EMF shielding blankets work — but quality varies significantly, and not all products on the market perform as claimed. 

    The physics behind EMF shielding fabric is established and well-documented. The variables are material quality and whether the product has been independently tested. The DefenderShield blanket uses two layers of advanced wireless shielding fabric — for increased efficacy — that have been independently lab-tested to reduce wireless EMF radiation by up to 99% across 300 Hz to 10 GHz. You can verify this yourself with a basic RF meter: hold the meter near an active device, then place the blanket between the meter and the device. The reading should drop significantly. Since it is not an official testing environment and uses a consumer-grade meter, at-home RF testing is typically not 100% accurate, but should show relative increases and decreases. If it doesn’t, try to troubleshoot and make sure you don’t have an active RF signal on both sides of the blanket, which can disrupt the readings.

    Yes — your devices remain fully connected and functional while you are covered. 

    This is one of the key design intentions of the blanket: you can work on a laptop with the blanket across your lap, scroll your phone in bed, or stream video on a tablet — all while the shielding reduces the radiation that would otherwise pass through to your body. The blanket is positioned between you and the device, not wrapped around the device itself. WiFi, Bluetooth, 4G, and 5G connections are all unaffected. The only thing that changes is how much of that radiation reaches your body.

    Yes — the blanket is designed for use with the whole family, including newborns. The exterior is crafted from a premium blend of 70% Bamboo Viscose and 30% Cotton— naturally soft, designed for durability and free from harsh chemical finishes, along with being sustainable and eco-safe. The built-in hood carries the same EMF shielding as the blanket body, allowing you to wrap infants securely with protection around their head. Safety Note: Use as a safe swaddle from day one until your baby starts rolling. To follow SIDS safety guidelines, wait until your little one is at least 12–18 months old before using this as a loose blanket in the crib. For pregnancy, many customers use the blanket over the lap and abdomen during laptop use, or over the torso during sleep near wireless devices.

    The DefenderShield EMF blanket reduces wireless radiation across 300 Hz to 10 GHz, which covers: Radio · 2G-4G cellular · 5G Low-Band · Bluetooth (2.4 GHz) · WiFi (2.4 GHz and 5 GHz) · 5G Mid-Band. This range covers the wireless signals most people are exposed to daily from phones, laptops, tablets, WiFi routers, and 5G cellular networks. It does not cover 5G millimeter-wave (mmWave) frequencies above 10 GHz, which are currently limited to dense urban environments and fixed wireless installations. It does not block ELF (Extremely Low Frequency) radiation from devices, so we recommend for direct contact protection to use with a DefenderShield hard-sided phone or laptop shield that includes our Ultra Armor+ shielding technology. For most everyday wireless technology exposure scenarios, the 300 Hz–10 GHz range is the relevant protection window.

    The shielding layers inside the blanket function as a floating ground — they intercept wireless EMF radiation and force the electromagnetic energy to take a longer, more indirect path through the conductive material, where it is absorbed and dissipated as a negligible amount of thermal energy within the shielding itself. Position the blanket with the shielding between you and the EMF source for maximum effect. Think of it like the lead bib at a dentist's office, but engineered specifically for RF and wireless frequencies rather than X-rays.

    Hand wash only, cold water, mild detergent, air dry. Machine washing and tumble drying will degrade the metallic shielding fibers over time and are not covered under warranty. The simplest solution for everyday care is to use the optional duvet cover: it is 100% machine-washable cotton sateen and fits perfectly over all four blanket sizes. Because the duvet cover takes the daily contact and staining, you rarely need to wash the shielding layer itself — dramatically extending its life. If you do need to wash the blanket directly: use cold soapy water, handle gently, avoid wringing, and hang to air dry completely before use.

    Choose based on your primary use: Small (36" × 35") — lap coverage during laptop use, for children, or travel. Throw (60” x 45”) — covers most or all of one person while working or resting on a sofa or in a chair. Medium (75" × 53") — full blanket or comforter  for one person while sleeping or lounging. Large (80" × 60") — generous single-person coverage or shared use between two people on a Queen bed. X-Large (84" × 75") — best for covering two people, covers the top surface of a  king mattress for sleeping (note: covers the top only, does not extend down the sides).

    Yes — This blanket blocks all wireless signals from your body, so is definitely worth the investment if your laptop is connected to WiFi or other wireless connections. Laptop use on the lap is one of the most direct and high-exposure EMF scenarios in everyday life. The DefenderShield blanket, draped across the lap with the laptop on top, places two layers of independently tested wireless shielding between the device and your body. Your laptop continues to work normally. However, the blanket does NOT block Extremely Low Frequency (ELF) emissions that emit from your laptops power supply, as the shielding needed to block ELF is thicker and less flexible and soft. For users who spend hours each day working on a laptop directly on your lap, we advise that you still pair it with the DefenderPad for additional heat and ELF protection from the underside of the device.

    Yes — it is designed for daily and nightly use. Many customers use it as their primary blanket during sleep to reduce ambient WiFi, cellular, and Bluetooth emissions in the bedroom environment. The bamboo-cotton exterior is soft enough for overnight contact For nightly use, the optional duvet cover is strongly recommended: it keeps the blanket clean between hand washes, makes care easy, and extends the shielding layer's lifespan. The Large size covers the top of a queen bed and the X-Large size covers a king mattress top for couples to use during sleep.

    Four specific, verifiable differences: (1) Independent lab testing — shielding effectiveness to 99% across 300 Hz–10 GHz is verified, not self-reported; most budget EMF blankets provide no published test data. (2) Multiple layers of shielding — for even better efficacy.  (3) EMF-shielded hood for infant swaddling — a design feature unique to DefenderShield in this category. (4) Optional made-to-fit washable duvet cover — extends the life of the shielding layer; budget alternatives do not offer a compatible care solution. Long-term quality is also backed by a 1-year manufacturer warranty versus the 30-day typical on Amazon alternatives.
