Packed with protection and utility, Dynamic protective pants are a great go to for anyone using a chainsaw. The nylon/spandex outer shell allows for stretch and durability while the knees are reinforced with Aramid/spandex for when bending and climbing are part of the job. The inner material is UL® classified and made up of six layers of Avertic® Pro by Engtex®, covering the leg from the waistband to the ankle. This material is cut-retardant, designed to clog the sprocket and stop the rotating saw chain of a gasoline-powered chainsaw. Not to worry, despite its numerous components, this material is easy-to-wash and dry. With two side slit pockets, one back pocket with zipper closure and a cargo pocket on the leg, your jobsite tools can be kept within arm's reach in these pants. They even have a side cell phone pocket with hook and loop closure.
