The jersey fits great, looks great and feels great! I would adhere to their advice that if you plan on wearing pads underneath it, size UP. I don't wear pads under my jersey and this jersey fits almost a little TOO perfect. When I extend my arms to the bars, the sleeves pull up a little but it doesn't bother me. I knew by ordering my true size that I'd be risking it being a tad tighter. I love the overall fit for cool weather riding. I can put a base layer under it and another layer over it if I need to. Another great product from Cognative!!
