EMF Blocking Phone Sleeve

Overview
We designed our EMF blocking sleeve to protect you when you carry your phone in your pocket.
Our proprietary RF shielding material blocks over 99.9% of cell phone radiation. But here is the catch. If we lined the entire sleeve with that material, your phone would lose all reception.
So, how do we fix that? We only line the backside.
This directional design creates a physical barrier between the phone and your body. It still provides a massive 91% to 96% effective reduction to the user, all without compromising your cellular reception.
Integrity: Watch Out For The Hype
Most EMF companies love to boast about "99% reduction." But what are they actually measuring?
Usually, they are only testing the raw material itself, not the real reduction you get when using the product. Let's talk about EMF stickers and pendants. If you stick a tiny radiation-blocking sticker on the back of your phone, your effective reduction is still zero.
Why? Because putting a waterproof sticker on your jacket isn't going to keep you dry in a rainstorm. Physics simply doesn't work that way.
To get real protection, a physical barrier must sit directly between your body and the radiation source. At RadiArmor, we only make products that provide genuine, measurable reduction to the user.
Features & Using It Correctly
-
91-96% Reduction: Lab-verified defense against high-frequency RF radiation.
-
Smart Design: Features a secure Velcro flap and a convenient belt loop.
-
Using It Correctly: Only the backside is lined with our shielding membrane. Always make sure the protected side is facing your body. Want to listen to music? Just tuck the flap inside so you can easily connect your headphones while keeping your body shielded.
Sizing
Our sleeve comes in two sizes: Large and Extra Large.
Because almost everyone uses a phone case, your size depends on the total footprint of your device. Grab a ruler and measure the length of your phone with the case on. If it measures 6.5 inches or less, choose size L. If it is over 6.5 inches, select size XL.

FREQUENTLY ASKED QUESTIONS
Will my phone still have a signal?
Will my phone still have a signal?
Absolutely! This is NOT a Faraday bag that blocks 100% of signals. Our sleeve uses directional shielding. Think of it like a welding mask. It acts as a physical shield blocking the intense energy traveling toward your body, while allowing the signal to freely exit the unshielded side.
Why is the effective reduction 91% to 96% instead of the full 99%?
Why is the effective reduction 91% to 96% instead of the full 99%?
Our proprietary shielding material blocks over 99% of the RF radiation that hits it directly. So, why doesn't it block the full 99% for your body? Because of how the sleeve is designed to keep your signal alive.
Think of your cell phone like a bare, glowing light bulb in a dark room. If you hold a thick piece of solid cardboard directly between your eyes and the bulb, the cardboard blocks 100% of the light shining straight at your face. But what happens at the edges? A little bit of light still spills out around the sides of the cardboard.
RF radiation acts the exact same way. Because we intentionally leave the front of the sleeve unshielded so your phone can still connect to the cell tower, a small amount of radiation "spills" around the edges of the fabric. Depending on the specific size of your phone and exactly how it sits in your pocket, that tiny bit of edge spill accounts for the 4% to 9% variance.
How do I test my sleeve at home?
How do I test my sleeve at home?
Real protection should be measurable. We actually want you to test our cases. But testing can be surprisingly tricky if you don't have the right equipment.
First, make sure you are measuring the right thing. Our cases are engineered to block high-frequency RF radiation from cellular networks and 5G. They do not block low-frequency magnetic fields (measured in milligauss).
Second, watch out for overly sensitive meters. What happens if you put a highly sensitive RF reader directly against an active smartphone? Even with a massive 91% to 96% reduction, the remaining radiation might still completely max out your meter's display. It makes it look like the case isn't doing anything.
Think of it like testing a blinding flashlight with a hyper-sensitive light meter meant for a darkroom. If you point the flashlight at the meter, it maxes out instantly. If you put a thick piece of cardboard in front of the flashlight that blocks 91% of the light, it is a massive drop in brightness. But to that hyper-sensitive meter? The remaining light is still enough to push the needle completely off the charts.
To get an accurate reading, you need an EMF meter with enough dynamic range to measure the actual drop. Want to see exactly how to do this? Watch our video on how to accurately test your case, where we demonstrate exactly what to look for using several popular EMF readers.
