A cycling Uniform is cut long in the back to accommodate the bent-over position used in sport-oriented cycling. … The cycling jersey is usually worn with a tight fit in order to reduce air resistance. Uniforms are made from a material designed to wick moisture from the skin, keeping the cyclist cooler and more comfortable. Cycling shorts (also known as bike shorts, bicycling shorts,or spats or thigh cling shorts) are short, skin-tight leg wear designed to improve comfort and efficiency while cycling.
