• 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.)
