whatever the pants are made of it isn't soft comfortable corduroy. i wear corduroy pants in the winter. maybe its the beford adjective. whatever this stuff is when it comes out of the dryer its so wrinkled it has to be ironed. i washed it in cold water and followed the instructions. its just poor quality badly fitting cheaply made goods that are always readily available. i was disappointed in calvin klein. i have bought many things from them and this is a dud. i will buy from them again.
