Whats up with all that lycra?
Again, modern cycling clothing strikes a balance between comfort and aerodynamics. Shorts and jerseys are cut to fit well in the riding position, their tight fit avoids chafing or, worse yet, dangerous tangles with moving parts, and the fabrics are designed to wick sweat away and keep the rider cool. At the same time, the clothing offers an aerodynamic profile. Wind resistance is a cyclist’s worst enemy, so the last thing one needs is a baggy shirt flapping in the breeze. If I ride with cycling clothes, I forget I’m wearing them, but if I ride with regular clothes, they always cause some kind of problem.
