PERSONAL SAFETY EQUIPMENT · TOP RATED
TrailGuard 3-in-1 Personal Safety Alarm
120dB Impact Loudness
IPX4 Shielded
72g Ultra Lightweight
After eight weeks of daily carry and a full outdoor testing cycle, the TrailGuard earned the highest alarm-clarity score in its class. It survived light rain without issue, and its weight was low enough that testers forgot they were carrying it at all. This is the alarm we now recommend first.
