Cyclists get a bad rap when it comes to clothing. Yes, it is true that most cycling clothing involves spandex. Yes, it is true that some people should never, ever, ever be allowed to wear that material. However, the fact remains that cycling clothing is designed as it is for specific reasons. Cycling shorts and jerseys, especially those designed for racing cyclists, need to be close fitting; baggy clothing can have a seriously detrimental effect on the aerodynamics of a cyclist, which for a racer, can be calamitous. Also, if a cyclist's clothing is not at least reasonably tight, there is a greater likelihood that it will become twisted or bunched, which can lead to chaffing and general discomfort. Cycling clothing needs to permit a cyclist maximum comfort without getting in the way. As a result, the clothing used by racing cyclists today is sleek, formfitting and usually heavy on the spandex.

Cycling shorts are easily recognizable. This was not necessarily the case 20 years ago, during the 1980s and the heyday of spandex. Today, however, only cyclists, only cyclists wear spandex shorts. These items of clothing usually come to mid-thigh, and most designs come to the waist like typical shorts. High-quality shorts have a number of features designed to improve fit and comfort. For example, a pair of shorts sewn from a number of smaller fabric panels will fit better than a pair made from larger panels. Similarly, good cycling shorts will feature a comfortable shammy, which is a lining on the inside of the crotch and behind of the shorts.

Some cycling shorts are bib shorts; these feature suspenders and actually cover part of the torso. Bib shorts have the advantage of being warmer than those that end at the waist. They can also be more comfortable, because they do not constrict the wearer at the waistline. Bib shorts sometimes feature mesh material on the part that covers the torso, which allows the wearer to breathe easier and remain cooler.

Cycling jerseys are especially desirable in more humid climates. They are made from lightweight, perforated materials that wick sweat away from the body. This can make a significant impact on the comfort of the cycler, and hence on his performance. In order for the moisture-wicking fabric to function best, it must be in contact with the skin. This means that cycling jerseys are often extremely tight, showing every curve of on the body. These jerseys also often feature pockets in the small of the back, and the garment's tightness prevents any items in these pockets from bounding around.

It is possible to purchase cycling jerseys that are designed to be relatively loose. These jerseys are often worn by cyclists who are less concerned with aerodynamics, such as mountain bikers. Chest and elbow pads can be worn beneath these jerseys, and such protection is often useful to mountain bikers. As long as the jersey is still of a good-quality wicking material, it will still keep the cyclist reasonably cool. Also, the looseness of the fit allows for more airflow beneath the jersey, which can contribute to the comfort of the wearer.
