it depends on how big you want it. it'll fit you nice with a big of sag. compared to oakley it's pretty similar, maybe a bit bigger. for comparison, i have a XXL ronin jacket and it goes down to my knees and i'm almost 6 foot.
i have xl burton( a little smaller than ronin) and im 5'8, its pretty baggy on me. theres a picture of it in my pics but the picture is really weird. the suit is actually way baggier. the tall tee is at my knees and the jacket goes halfway to my knees in the picture and the pants are all bunched up and non baggy looking but the pants are actually the baggiest part of my suit.
well.......that was a long explanation. i hope it helps
