i have the XL benjamins. im 6'3 170lbs. and thin. they fit "loose" on me. there not a baggy park fit but its like perfect for big mountain riding and powder. I wouldnt suggest the benjamins because your 200lbs so there probubly gonna be snug on you. Id post pics but im in the proccess of moving and only have starbucks internet. hope that helps
as for jacket, XL, and the orage pants, if you can search out an XXL, that'll be your best bet. Orage's stuff is sick, but a lot of it isn't as baggy as other manufacturers, so you usually have to go a little bit bigger.
Benjamin pants are made kinda small. You should really try to get them in xxl but if you can't you can always get them in xl. I got the brown ones last year in L and I am 6'0 now and they are too small. Hope that helps
