I have some DNA pants form last year andDNA measures pants by waist size, not s, m, l, XL etc. etc.
They are like 42's or something and they fit pretty damn big, about the same as XXL Oakley Puffy's. And they are super tech pants, 20k/20k and I've never been wet or damp even in pouring rain. Best quality gear I've seen out of any company.
