What items particular Are you looking to compare? I wear Medium for all Rapha/Sportful/Castelli gear, the exception being Large for Castelli/Sportful bibs.
OK thanks. I seem to be M in everything up till now, Castelli, Rapha, Assos. I was looking at the Fiandre bibs and Jersey.
A few years back I tried some hotpack Gilet's but the sizing was odd and I think I found the XL a good fit.
Anyone own some Sportful as well as Rapha and can tell me how they compare size wise?
