At Trail.nl, your safety is our top priority, especially during those solo runs in the early morning or late evening. That's why we offer a powerful emergency alarm that is specially designed to give you an extra layer of protection. With a simple pull on the pull cord you activate a 120 dB alarm, powerful enough to warn passers-by and deter potential attackers. This alarm can be heard from more than 600 feet away and is as loud as an ambulance siren.
