The material is very limp, somewhat coarse, polyester with some texture to it (ie. not super smooth).  Fitment is excellent.  I am 6' and 185lb and the mediums fit me very well.  Love the tapered leg.  Use this pant for biking and jogging.  I wouldn't say this is a high end pair of pants but when it fits this well, it is money well spent.  I also like that the bottoms have zippers and the side pockets have zippers.
