Complete Functionality Overview

Unrivaled EMF Radiation Defense: Halsa’s Silver-fiber Interior

Halsa’s innovative interior, lined with 100% pure silver-fiber fabric, offers unparalleled protection. It blocks over 99% of electromagnetic field (EMF) radiation from mobile devices, ensuring you’re safe from harmful radiation while preserving your signal for calls and texts.

Robust Signal Reduction Technology

Designed to isolate devices from electromagnetic noise, Halsa attenuates WiFi (2.4/5GHz), Bluetooth, 5G cell signals, GPS, RFID, and radio frequencies by 60-80dB. This technology protects a range of electronics, including cell phones, smartwatches, two-way radios, and GPS units, without compromising essential communication.

Universal Design with Secure Fit

This pouch, measuring 4”x8”, features a drawstring closure, accommodating most smartphones, including the iPhone 15 Pro Max and Samsung Galaxy S25 Series. Ensure a perfect fit for reliable shielding every time. Confirm your device’s size to guarantee a secure and effective fit.

Proven Effectiveness Testing

Test Halsa’s shielding power accurately using an EMF meter to compare RF and microwave emissions inside and outside the pouch. Note that testing by calling a phone inside the sleeve is not a valid method.
