The DYNAMIC wrap chaps are made from water- and oil-resistant Cordura nylon, a tough material with exceptional abrasion resistance that provides long-lasting comfort. They also feature Avertic Pro by Engtex, a cut-retardant material designed to reduce the risk of severe injury in the event of contact with a rotating saw chain. They have an extra 12 in back flap on the lower leg for better coverage from briars, thickets and heavy ground cover. In addition, these chaps feature a cargo pocket for quick storage on the left leg panel as well as a 1-1/2 in interlocking waist buckle that adjusts from 30 to 42 in (optional waist extender, sold separately, fits waists up to 56 in).
