I purchased a size 42 after reading so many belt reviews saying they'd purchased too small.  I wear 38" pants, so went two sizes up.  Should have only gone one size up.  The 42 belt is too big, so I will return it.

However, the quality of the belt is superb.  I've ordered a size 40 belt because I liked what I saw.  When that one comes, I expect I will rate it a five-star.

Other reviewers are correct, this is a wide belt.  The belt description says 40mm; one should hold a scale against the pants to be worn with this belt.  I will be wearing it with Docker type pants and it barely fits.
