Way too small! I wear a 31x30 in American sizes and I ordered a 31 waist not thinking and he could not even get them past his thighs! I ordered him some of these a couple of years ago and knew that they had to be a larger size, I was just not prepared to try and figure out just how much of a bigger size I need to buy. I'm going to try a 34 this time but hope and pray they fit this time! The last couple of pairs I purchased I had to take them and have the button moved as it was WAY to far off but I guess it is what it is when you're trying to save a buck! He is an over the road truck driver and these black pants are part of his uniform and these have been the most durable long lasting pants that we have come across!
