DSCP Quarterdeck Collection white dress pants size 40R. Proven established quality, you know what these are. That said I think they are polyester but it does not specify. These came from a military store closing liquidation, they had a price sticker pinned to one of the legs where there are tiny pin holes but nothing has been hurt; due to the handling between the factory and me they will need to be pressed before wear and then they will look crisp and sharp from top to bottom. If they were fatigues I would say put them straight on, but obviously a dress uniform is pointless unless it is really sharp. Total bargain price.
