So, my 2014 large top turned up yesterday, comparing to a 2012. Better quality zip and reinforced pockets, so both my moans resolved, fabric is still midweight but has some lighter vented stuff under the pits, so should be a bit cooler but still not a high temp jersey (for me).
Overall much nicer, but then again they’ve gone up in price
Sizing as above, large in castelli is skin tight on me (can see my lumpy collar bone…) Morvelo is a little bit bagger still a good fit. The sleeves however are really tight not sure if this is a trend for ‘compression’ stuff but my arms aren’t that big. I’d say if you have decent sized biceps you might struggle!
