Good to know

This sleeve uses Ultra Armor+ Shielding Technology in the back panel, providing directional protection between your laptop and your body. For EMF protection, the back of the sleeve must be positioned between the bottom of the laptop and your lap. The sleeve also reduces heat transfer from the laptop to your body. When carrying the laptop inside the sleeve, keep the shielded backside facing your body for continued EMF reduction during transport.
Description

Block the Radiation and Heat Your Laptop Pushes Into Your Body

Every laptop emits two things from its underside that your body absorbs during lap use: electromagnetic radiation (RF from WiFi, Bluetooth, and cellular connections, plus ELF from the battery and circuitry) and heat from the processor, battery, and internal components. The longer the session, the higher the cumulative exposure.

The DefenderShield® Laptop EMF Radiation Protection Sleeve places Ultra Armor+ Shielding Technology between the bottom of your laptop and your body. The shielding layer in the back of the sleeve blocks up to 99% of directional EMF radiation from 60 Hz to 2.5 THz - covering all three 5G bands, 4G LTE, WiFi, Bluetooth, GPS, NFC, and RFID. The “+” in Ultra Armor+ means ELF shielding from the battery is included - the frequency band that most competing laptop shields leave out entirely. The multi-layer construction also acts as a thermal barrier, reducing the heat that transfers from the laptop to your lap.

It’s a laptop carrying sleeve with a built-in radiation filter - your laptop sits on top while you’re using it, the shielding and insulation sit between, and your body stays protected.

Stay protected with Ultra Armor+ technology. EMF shielding performance verified through FCC-accredited lab testing.

A Carrying Case, a Lap Shield, and a Stand - in One Sleeve

The sleeve is built from premium vegan leather with neoprene stretch siding that expands to fit thicker laptops. The padded interior protects the device from scratches and impact during transport.

Remove the laptop and place the empty sleeve flat on your lap - it becomes a non-slip lap shield. Flip the VELCRO flap outward to expose the non-slip interior surface, which grips the laptop and prevents sliding. For an elevated typing angle, fold the flap into a triangular backrest and lean the back of the laptop against it - improving ergonomics and airflow at the same time.

When you are done working, slide the laptop back in, close the flap, and carry it. The sleeve fits into backpacks, briefcases, and tote bags without adding bulk.

Available in two sizes - up to 16” and up to 17.3” - compatible with MacBook Pro, MacBook Air, Chromebooks, Surface™ Pro, and most PC laptops.

Key Features
🛡️ Ultra Armor+ Full-Spectrum EMF Shielding The back of the sleeve blocks up to 99% of directional EMF radiation from 60 Hz to 2.5 GHz - covering RF from WiFi, Bluetooth, cellular, GPS, NFC, RFID, and all three 5G bands, plus ELF from the battery. Unlike most laptop shields that address only a small portion of RF frequencies, our shielding blocks the full RF and ELF spectrum emitting from your device. Verified by an FCC-accredited lab. 🔥 Thermal Barrier - Reduces Heat Transfer The multi-layer construction does not just block radiation - it also insulates against the heat generated by your laptop’s processor, battery, and internal components. Long sessions on the couch, in bed, or at a desk become more comfortable when the thermal energy stays on the device side of the sleeve. 💼 3-in-1: Carrying Case, Lap Shield & Ergonomic Stand Slide the laptop in for padded travel protection. Lay the empty sleeve on your lap as a flat shield. Fold the VELCRO flap into a triangular backrest for an elevated typing angle with improved airflow. One product, three configurations, no accessories needed. 📱 Universal Fit - Mac & PC, Up to 17.3” Neoprene stretch siding expands to accommodate thicker laptops. Available in two sizes: up to 16” and up to 17.3”. Compatible with MacBook Pro, MacBook Air, Chromebooks, Surface Pro, and most standard PC laptops. 📡 Laptop Stays Fully Connected

The shielding is directional: it blocks EMF radiation from passing through the back of the sleeve toward your body, and does not stop a signal from reaching the laptop’s antenna. WiFi, Bluetooth, cellular, and all wireless connections remain fully functional during use.

 🧪 Tested EMF Shielding Performance The Ultra Armor+ shielding technology used in this product is verified to block EMF radiation from 60 Hz to 2.5 GHz by an independent FCC-accredited laboratory. See our testing result on Our Technology page.
How to Use

Using as a Lap Shield

1. Remove the laptop from the sleeve. Place the empty sleeve flat on your lap.

2. Set the laptop on top of the sleeve. The shielding layer is now between the bottom of the laptop and your body. EMF radiation and heat from the laptop are reduced at the point of contact.

3. For a non-slip surface: flip the VELCRO flap outward so the non-slip interior material faces up. This grips the laptop and prevents it from sliding off your legs.

Using as an Ergonomic Stand

1. Fold the VELCRO flap into thirds. Secure it into the slots on the sleeve to form a triangular backrest.

2. Lean the back of the laptop against the wedge. This elevates the screen to a more comfortable viewing angle and tilts the keyboard for easier typing.

3. Improved airflow. The elevated position creates a gap underneath the laptop, allowing heat to dissipate more effectively than when the device sits flat on your lap.

Using as a Carrying Case

1. Slide the laptop into the padded compartment. The soft interior cushions the device against scratches and minor impacts.

2. Close the VELCRO flap. The flap holds the laptop securely inside during transport.

3. Keep the shielded back facing your body when carrying. Even when the laptop is stored inside the sleeve, it continues to emit EMF radiation if it is not completely powered off. Orienting the shielded back toward your body reduces exposure during transport in a backpack, briefcase, or tote bag.

Care Instructions

• Wipe the vegan leather exterior with a soft, damp cloth and mild soap. Allow to air dry completely.

• Keep the VELCRO closure free of lint and fabric debris for a reliable seal.

• Avoid storing heavy objects on top of the sleeve, which could compress the padding.

Laptop EMF radiation protection

I like the steadiness of it, I have a 13 inch laptop that fits in it perfectly but it says it can fit up to 15 inch. I think that would be really tight getting a 15” in and out. That’s the reason I took one star off because I think it’s a little misrepresented

The best products, and customer service.

Dear Defender, Shield staff,

I’ve been a long-term customer, and have been satisfied with all of my purchases, except for the phone holder for the car. I have a Prius, and I could not successfully get it into my air vents.

The other product that I bought was a pouch for my iPad. I thought that I could use it while laying in bed, however, when I tried to use it, due to the material, it the iPad kept sliding off. Consequently, I will buy a case, which is really what I should have bought initially. You live and you learn. Or, not.😉

Having said that, I just want to thank you for continuously developing products to protect us from 5G. Thanks sweetheart all you have to do is tap on the left side of the plus side

It works!

I just recently discovered the truth about radiation from laptops, so I did some research and found DefenderShield. Once I got the laptop protector, I used my new EMF meter. This device proved just how much radiation was coming from my laptop, and the before and after numbers were shocking! By using the protector, the radiations levels are now in the 'safe' zone, and I am a happy camper!

FREQUENTLY ASKED QUESTIONS

Laptop EMF Radiation Protection + Safety Sleeve FAQ

In the back panel - the surface that sits between the laptop and your lap. When the sleeve is placed flat on your legs with the laptop on top, the Ultra Armor+ shielding layer is between your laptop and your body. This configuration blocks directional EMF radiation and heat from the bottom of the laptop from reaching your lap.

Yes - this is one of the key differentiators of the DefenderShield Laptop Sleeve. RF (Radio Frequency) radiation is emitted by your laptop’s wireless connections: WiFi, Bluetooth, cellular, and 5G. ELF (Extremely Low Frequency) radiation is emitted by the laptop’s battery, power supply, and internal circuitry. Most laptop shields that claim EMF protection address RF only, and not even the full spectrum of higher, newer RF frequencies. The Ultra Armor+ shielding in this sleeve blocks both - from 60 Hz (ELF) through 2.5 THz (5G mmWave) - making it comprehensive across the full electromagnetic spectrum relevant to laptop emissions.

Yes - the Ultra Armor+ shielding covers all three 5G bands: low-band (below 1 GHz), mid-band/C-band (up to 6 GHz), and high-band millimeter wave (24 GHz and above, tested up to 2.5 THz). Many competing EMF laptop shields address only low-band frequencies. The DefenderShield sleeve shielding is independently tested to perform across the full 60 Hz - 2.5 THz range.

Yes - the multi-layer construction acts as a thermal barrier. Laptops generate significant heat from the processor, battery, and internal components, especially during demanding tasks. The sleeve’s construction reduces the amount of thermal energy that transfers from the bottom of the device to your lap, making long work sessions more comfortable and reducing the risk of skin discomfort.

No - all wireless connections remain fully functional. The shielding is directional: it reduces the radiation passing from the bottom of your laptop toward your body, not the signal reaching the laptop’s antenna. WiFi speed, Bluetooth pairing, and battery performance are unaffected.

The VELCRO flap folds into a triangular backrest. Fold the flap into thirds and secure it into the slots on the sleeve. It forms a sturdy wedge that you lean the back of the laptop against. This elevates the screen for a better viewing angle, tilts the keyboard for more comfortable typing, and creates an air gap underneath the laptop for improved heat dissipation.

Most laptops up to 17.3”. The 15.6” sleeve fits laptops with displays up to 16 inches (16.50” × 11.25” outer dimensions). The 17.3” sleeve fits laptops with displays up to 17.3 inches (17.75” × 12.00”). Neoprene stretch siding accommodates thicker laptops. Compatible with MacBook Pro, MacBook Air, Chromebooks, Surface Pro, and most PC laptops.

The Sleeve is a 3-in-1. The DefenderPad is a sturdy lapdesk. The DefenderPad is a rigid, fully non-slip lap shield that lies flat between your laptop and your legs. It provides maximum surface grip and heat-blocking capabilities but is not a carrying case.. The DefenderShield Laptop Sleeve is a  lightweight EMF shield, a padded carrying case that folds into an ergonomic stand. Choose the DefenderPad if you want the sturdiest possible flat shield. Choose the Sleeve if you want portability and an ergonomic stand for your laptop.

The sleeve contains Ultra Armor+, which is different from the Ultra Armor® used in Faraday bags. Both use multi-layer metallic composite shielding. The difference is intent: a Faraday bag seals the device completely inside a conductive enclosure, blocking all signals in and out. The sleeve only contains shielding in the back panel, so your laptop stays connected while reducing the radiation that reaches your body. Ultra Armor+ includes ELF shielding on top of the RF protection - a layer the standard Ultra Armor® Faraday line does not include due to the rigidity of the ELF shielding layer.

A standard sleeve was designed to carry your laptop. This one was designed to shield you from it. Every laptop sleeve on the market pads and protects the device during transport. None of them contain a shielding layer for the full range of EMF radiation and heat your laptop pushes into your body during every lap session. The DefenderShield Sleeve adds a verified directional EMF shielding layer and thermal barrier, plus an ergonomic stand and non-slip surface. Same bag, more protection, better posture.
