Rapha, nice but a bit pricey?

I have a v1 Lightweight Jersey and it is a slightly smaller fit than the Classic Jersey, but the design of the Lightweight has changed since then - I think they're not even using the same material as the first ones.

I don't own any PT stuff but I'd wager it's not as snug as that. Maybe somewhere in between Classic and PT.

Cheers.

Tricky then.
My XL PT jersey is about Perfect. But I wouldnt want any looser in a lightweight, as it wouldnt be layered so much.
My L tribute jersey is as tight as I can og without splitting something I reckon.

Probably just stick to XL/M.
