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.
