Wow. What a great kit. I hemmed and hawed and finally took the plunge to buy this and I'm glad I did. This suit is SO comfy. I would say that the Sanremo suit is to a regular jersey and bibs as bib shorts are to regular bike shorts. The one-piece construction is such a good idea; riding with the top unzipped produces much less flapping than a jersey would, and bathroom breaks are easier in these shorts than any pair of bibs I've ever owned.
A couple of tips though; I usually wear "Euro" or "Racer" cut jerseys, and so the tight fit wasn't off-putting. If you prefer a looser fit then this isn't the kit for you (it's essentially a skinsuit). Also, make sure you size up; I wear Medium bibs in every brand except Assos (Large) and I got an XL Sanremo and it's not too big.
