Ray Prevostwrote a review of Pearl Izumi P.R.O. Leader Jersey - Men's on February 4, 2016
I normally wear a medium jersey, but since I was at the top end of the sizing chart for medium, I went with large. I'm glad I did. The Large is snug on my chest, and just right on my arms, which are big for my size.. The one place the fit isn't so good is in the back. It's both too long and too loose. But I'm glad I didn't go with a smaller size as it would not have fit elsewhere. I did like the P.R.O. enough to buy a second one in a different color.
