I read the reviews and some say the 501s are not shrink to fit.  I have to say that I'm confused by this because it seems some are shrink to fit and others are not.  I bought one pair of the rigid 501s in 35x30 and they fit perfect from the first day.  The second I bought were the same size but they shrunk so much I gave them to my nephew.  I then re-ordered a pair in one size larger, 36x32, washed them and they fit perfectly.  Now I don't know how to order.  I cannot keep ordering and re-ordering jeans.
