My LBS has a sale on right now for their Primal Jerseys. I want to get one, but I am not sure of what size to get because of my body type. I'm 6'0 and 145-150lbs, and i'm 17. I am not sure whether to get the medium or the large. My weight is mostly from my lower body, but I have a long(ish) torso. When I tried the large on it felt a little loose, but it was the right length. The medium fit me tight around the hips/waist, but it felt a little bit short. Is there any specific guidelines that jerseys should fit by, or is it just personal preference. I mostly wear size large in normal t-shirts because I like them a little bit loose.
