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.)
