Byrna Duo – Personal Safety Alarm + Pepper & Tear Gas Defense System

The Byrna Duo is a powerful compact self-defense tool that combines an ear-piercing 130 dB personal safety alarm with a pepper spray and tear gas canister — all in a device that fits comfortably in the palm of your hand. Designed for everyday carry and quick access, the Duo gives you two layers of protection to help you stay safe in any situation.

Unlike traditional personal alarms or disposable sprays, the Byrna Duo features a rechargeable battery and a reloadable defense spray compartment, allowing you to replace the canister after use without buying a whole new device. Lightweight, discreet, and easy to operate, it’s perfect for walking, commuting, travel, night shifts, college campuses, and anyone who wants reliable, non-lethal protection.
