mine were pretty similar to Levi's and Dickies, but the hem seemed to be longer. (I'm 5'7 and bought the "Short".)
But I think its better to have a longer hem, because when I'm riding, the bottem of the shants?/knicker? is still an inch or two below my knee, so my knee-cap doesn't get any wind chill. I guess they just seem longer when I'm standing, but on the bike they totally make sense.
I was going to buy some Dickies, have a local seamstress take out the baggyness, and then hem them up, but it was going to cost a lot and I wasn't too sure of how long to tell the seamstress to hem them.
