I'm 6'3, probably 165 pounds, and would recommend the XL pants. The waist will be a bit bigger, but assuming you are still growing you will grow into them, and the length is just right, suspenders will help keep 'em up. As for the jacket, I believe an XL Fatigue is 37 inches? And I have a Bloom Sage Eclipse jacket, that is right around 37.5 inches, it is a little below mid-thigh when I have my pants, boots, and layers on, but I'm not sure how the two fit's compare. I would recomend XL, but it depends if you want a longer fit, or if you desire the clean-cut somewhat long fit.
