I know I know. You don't want to buy something so expensive! But do it! Buy the top and bottom! I coach track and Spring in Ohio is wicked chilly. These layers have helped keep me warm and comfortable. It has been suggested to wear tights underneath to protect from itchy wool, I haven't experienced any itching though. (I don't have sensitive skin.) Im 510 215 and I ordered the XXL. I could have worn the XL but I liked the length in the arms of the XXL.
