Instead of ordering online I went to a shop nearby to try on a pair. They didn't have the neopro s7 so I tried on the equipe s7 instead. My very first impression was: "oh wow".
Small fits me perfectly.

To be honest it fits much better than the rapha classic / pro bibs. I'm a huge rapha fan, but I must admit that even the entry / mid level assos bibs are superior based on the first impressions. We will see.
