Appear to me very well made, heavy duty zippers and the material is very thick, probably from the insulation. Wore them over a pair of thermals and was outside all day without feeling the cold in single digit temperatures. Chose these because I don't like suspenders or things hanging over my shoulders like bib overalls. You should buy these at least two waist sizes larger than your current pants size if you want them comfortably to fit over regular jeans or you will need a thinner layer under such as thermals/sweats. also go a size smaller on inseam or you may find them too long depending on how low you want the pant leg over your boot or scraping the ground. That's where the cordura ends help stop any wear. Great overall at a great price point. I would buy again if/when these wear out.
