I am giving a 4 but my heart says 3.5. I assumed they were the updated version of the Velocissimo which I really liked. These feel like the model below. The length is a touch long for my inseam. The chamois is ok but I havent used it for anything over 2.5 hours. There were a few loose threads I had to trim so I cant say the QC is what I expected. The price was fair so its a fine mid week bib.
