Unrivaled EMF Radiation Defense: Halsa’s interior, lined with 100% pure silver-fiber fabric, offers maximum protection, blocking over 99% of electromagnetic field (EMF) radiation from mobile devices. Advanced shielding reduces harmful RF exposure while preserving enough signal for calls and texts. Available in Grey, Black and Pink!
Robust Signal Reduction Technology: Engineered to isolate devices from electromagnetic noise, Halsa attenuates WiFi (2.4/5GHz), Bluetooth, 5G cell signals, GPS, RFID, and radio frequencies by 60-80dB. Protects a range of electronics—cell phones, smartwatches, two-way radios, and GPS units—without compromising essential communication.
Universal Design with Secure Fit: Measuring 4”x8” and equipped with a drawstring closure, this pouch accommodates most smartphones, including iPhone 15 Pro Max and Samsung Galaxy S25 Series. Confirm your device’s size for a perfect fit, ensuring reliable shielding on every use.
Proven Effectiveness Testing: Assess Halsa’s shielding power accurately—use an EMF meter to compare RF and microwave emissions inside and outside the pouch. (Note: Calling a phone inside the sleeve is not a valid test method.)

They work
These actually work great. I keep my phone in another medical device close to my bed using these help a lot. Great product highly recommend.

Fantastic
This was my trial bag to decide if I wanted to invest in or needed a true faraday bag. It sounds crazy but I heard that our phone and brain communicate via waves while we sleep and I swear I was having vivid and usually not good dreams, as well as waking in the night, often right before my alarm would go off. Since keeping my phone in this bag overnight (it’s my daily alarm) I have noticed NO weird activity and am very happy with it. I like the cinch cord because then I can have my phone charging while using compared to others which require a seal. I don’t need to completely cut off cell capabilities like receiving calls or texts so this is great for what I wanted.

I’m sleeping better!
I charge my phone and listen to sleep hypnosis right next to my bed. It’s weird but I haven’t needed to take anything to sleep in a while and pretty much sleep through the night without frequent wake ups.

Great Quality!!!
I love that this pouch is versatile. If you use it on your nightstand like me or taking it with you while running errands. It keeps the radiation at bay!

Only works fair.
According to my EMF meter, EMF leaks out of bottom of bag when tied shut.

color hard to find
Works as far as I can tell. however, the advertised pink is a pale flesh color and hard to find. I’m going to order a brightly colored one from another supplier.

Fits well.
Love this. Well made. Draw string works well. Good full fit for my phone.

Didn’t work
Oh this works for a small pouch to keep your phone in if that’s what you want. But most people are going to buy it to block the EMF radiation. Per my EMF meter, it doesn’t do that. I might as well wrap my phone in a paper towel. Easy return.

I wanted to return the item as after I did more research, I found out this items are ineffective at blocking. I have had no response from the seller since my request.
