Wearing protective apparel on the jobsite is critical – especially when cutting near active roadways. The Dynamic Hi-Vis Apron Chaps - 6 Layer feature Hi-Visibility Nylon Fabric that is visible by motorists traveling up to 50 mph. This meets the Class E reflective requirements and earns a Class 3 reflective rating when worn with the Class 2 reflective vest. The chaps also feature reflective ribbon made from 3M™ Scotchlite™ Reflective Material. And when it comes to cutting protection, these chaps include six layers of Avertic® Pro by Engtex® cut retardant material, designed to reduce the risk or severity of injury in the event of contact with the rotating saw chain on a gasoline-powered chainsaw.
