These pants last longer than any other double knee pants my Contractor husband has tried, and I love the way he can brush sawdust off so easily and not bring it in the house stuck to his pants. They last longer because they don't need washing as often as other non-jean "work pants" he's tried. He has an uneven waist size, and it is very hard to find pants that are available in those sizes. When he wore suspenders to hold up pants that were a bit too large in the waist because he could not get his exact size, the suspenders would tear up the waist band. So, having these in all sizes also makes them last longer for him. He thought they would be too hot where we live, but they are not any hotter than his previous work pants. He says he will wear these as long as he can get them.
