I purchased two pairs of these pants, at the same time, for my husband as a birthday gift.  I love the fact that you can get the right size leg with no alterations needed.  The khaki were fantastic, size and length perfect, the dark navy were a size smaller in the waist than they should have been, I returned them and ordered the same size again thinking it was maybe just a mistake with the one pair.  No, today the new dark navy arrived again, too darn small.  I have now re-ordered them in a size larger than required along with another pair in another colour in the size I do require.  I will let you know how the sizing works out this time.  My husband likes the pants so I guess it is worth all the trouble of shipping from US to NZ.  We cannot get pants here that are sized to the length required so it is really good value for us.
