When you need dependable， long-lasting protective apparel， STIHL has the solution. Using rows of heavy-duty zippers， the Dynamic Zip Chaps - 6 Layer provide full wrap-around protection for the lower leg area. The zippers run along the entire inseam of the chaps， helping to ensure a comfortable fit that is easy to put on and/or remove. The outer material is crafted from durable orange Cordura nylon fabric， an all-weather material used in a range of premium outerwear brands. Inside， the chaps feature 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. They are great protective chaps in both the heat of summer and the cold of winter.
