So im 5'11, 6 footish and about 155, 160 pounds. Normally i think a large would be a fine size for me, but i need this suit to fit me for the next two or three seasons and im pretty sure I am going to grow at least two inches, maybe more over the next couple of years, judging by the fact that everyone in my family is pretty tall. Is it a good idea for me to get a XL jacket and large pants if they have to last me for the next couple of seasons?
