Italian company, UYN, is a relatively new player in cycling clothing, having formed in 2018, but it's grown in prominence in a short space of time and even supplies undergarments to WorldTour outfit, Israel Start-Up Nation. For any brand, however, reputation and perception is going to be a decider in terms of market reception - and the one thing UYN has going for it is the distinct style, design and fabrics, which represent the complete antithesis to the current trends dominating the best cycling shorts segment. 

We've been testing the Biking Racefast Man bib shorts for the past five months in a variety of temperatures and riding conditions. Read on for the verdict.
