I am going to pickup a set to keep on my motorcycle, as i ride to work in the summer. For those of you that have them. Do you get a larger size to go over your cycle jacket? I wear an xl jacket so would i need a 2 xl? If i get the 2 xl the pants would be huge! I'm not sure how to size these. About a 36 waist 31 inseam. I wear a 46r dress coat. Suggestions?
