Using rows of heavy-duty zippers, the Function Zip Chaps - 6 Layer provides full 360º of protection for a user’s lower leg area. In addition to enhanced protection, these chaps also provide enhanced convenience. Rows of zippers run along the entire inseam of the chaps, helping to ensure an effective fit that is easy to put on and/or remove. The outer material is crafted from heavy-duty Black 500 denier nylon fabric. Inside, the chap features six layers of Avertec® Pro by Engtex® cut-retardant material, designed to reduce the risk or severity of injury to body parts in the event of contact with the rotating saw chain on a gasoline-powered chainsaw. The Woodcutter Protective Apparel is perfect for paired use with any of your Homeowner STIHL units. While designed for the occasional user, it still meets and beats the standards required for personal protective apparel.
