As a contractor, I often have to get into the thick of things; as a business owner, I have to look respectable. They are also comfortable. A fabric that is soft to the touch, unlike other Heavy Duty Pants made from canvas, or ripstop. These pants provide freedom of movement to let you Climb a rock, hike a challenging trail, buck a tree, or do anything you like. I purchased one size larger than my normal size and they are on the money. These are the best of the best. Worth every penny!
