Rapha Pro team base layer
Thinking of picking up a couple of pro team base layers but unsure of sizing. I have a good few Rapha jersey's all size medium and not Pro team. 5 foot 9 and about 11.5 stone with 40 inch chest. Should I go medium or large. I use an Asso habu over winter but its no good in the rain so the base layer would work good with that jacket.
