RadiArmor EMF Blocking Cell Phone Sleeve - EMF Blocking Pouch That Fits Most Cell Phones - Updated Version (Black, Large)
$27.50
in stock
Amazon.com
as of November 14, 2025 6:31 am
Features
- EMF PROTECTION: RadiArmor’s EMF blocking pouch is lined on one side with an EMF blocking fabric that blocks over 99% of high frequency RF and microwave radiation commonly associated with cell phones, WiFi and 5G. Effective EMF reductions to the user is between 91% to 96%. Please note, this sleeve is NOT intended to block all signals like a Faraday bag. This is designed to reduce your EMF exposure when you carry your phone.
- HOW IT WORKS: Only the backside of our EMF blocking sleeve is lined with our proprietary EMF blocking material, which is lab tested and verified by a third-party source. This creates an EMF blocking barrier between you and your phone while still ensuring normal cell phone reception.
- SIZING: This sleeve is designed for most standard-sized smartphones up to 6.1 inches (15.5 cm) in total length, including your case. Please measure your phone with its case to confirm it is less than 6.1 inches. If your phone is 6.1 inches or longer, choose the XL version for a better fit.
- INTEGRITY: Most companies who claim 99% EMF reduction refer to their EMF blocking fabric, not the EMF reduction you receive. Some companies even sell stickers and pendants with a tiny piece of EMF blocking material and claim 99% reduction, but the real reduction to you is zero or sometimes worse, especially if applied to the back of your phone. RadiArmor only sells products that provide real protection and is based on scientific principles.

RadiArmor EMF Blocking Hat – Unisex Hat with EMF Blocking Liner That Blocks Over 99% of High Frequency RF Radiation Black
$48.00
in stock
Amazon.com
as of November 14, 2025 6:31 am
Features
- OVERVIEW – RadiArmor’s unisex EMF blocking hat features a breathable liner made of woven silver fibers that blocks over 99% of high frequency RF and millimeter wave radiation commonly associated with WiFi, cellular and 5G communication.
- LAB VERIFIED – Breathable woven silver fabric is lined throughout the perimeter of the hat and is third party verified to block 99.9% of high frequency RF. Average reduction to the head inside the hat exceeds 90%. NOTE: This hat protects your head, not your whole body. Only a faraday cage can block RF from your whole body. When testing using an RF reader, please measure inside the hat. See testing instructions below.
- INTEGRITY: Many EMF protection products claim 99% reduction but are referring only to the radiation blocking material itself, NOT the protection you receive. Wearing a pendant that blocks EMF offers as much a protection as a waterproof pendant would protect you in the rain. At RadiArmor, we only make EMF protection products that provide real protection.
- SIZING – This unisex hat features an adjustable strap and is designed to fit most size heads. May not be suitable for size XL. Please see size chart.
- CARE – Silver is naturally odor resistant and rarely requires washing. If necessary, hand wash and hang dry only. Silver naturally changes color over time but this does not effect the EMF shielding capabilities.
