I'm not being a dick, but searchbar saga XL nd there is a thread called 'how saga will fit in Xl or something like that. There are loads of examples of people with their sizing and stuff.
It'll be easier and quicker for you.
i'm 6'0" 175 and i have size large and they fit like my oakley size xl, i need a belt for em, so i would go wit large unless you want them super baggy, in that case get xl
