Well what can I say about these pants, I have 3 pairs of the 4.0, 2 pairs of the durastretch cargo’s, 4 pairs of the NYCO double front cargo’ pants see where I’m going here! Been a tradesman for over 20yrs now bricklaying, tiling, carpentry you name it, I fit kitchens and bathrooms professionally and do all my own work. These pants hold up, I like the 4.0 mostly cause they are so damn comfortable and tough. I’d say if I’m on my knee pads setting floor tile etc I’ll wear the NYCO cargo’s cause the price is a little less and don’t mind getting them filthy. Folks don’t waste your money on cheap alternatives buy quality you’ll save in the long run, and you feel great in them, exact same mind set when buying decent tools.
