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.)

Great!
Easy to use and hopefully reduces EMF in our home. Very reasonably priced and good quality. Easily fits my iPhone and cinches together to close leaving room for charger to hang out.

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!

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.

USELESS/DON’T BUY
According to my reader device, it doesn’t shield AT ALL!

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.

So far, so impressed!
I’ve had this for about a week and so far I am impressed! I almost always put my phone on airplane mode when I sleep but now I have added the extra layer of protection using this bag and I honestly feel like I wake up less during the night. I tested it by keeping my phone on as normal and then put it in the bag. I pulled it out and for those first few seconds I saw ‘No Service’ and even had my mom call me to test it and the call never came through, which is EXACTLY what I wanted in a bag like this! I haven’t had it long but do not anticipate any disappointment! Will be recommending to friends and family who wanna reduce EMF exposure. 🙂 Plus, it’s dang cute!

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.
