According to Danielson, form-fitting bike shorts protect your body while cycling, helping to prevent numbness, chafing, and general discomfort on the saddle. "They are also made from moisture-wicking fabric that will keep that area dry, which is crucial for us women," she adds. Additionally, the compressive nature of cycling shorts can increase the flow of oxygen to your thighs and glutes. "They can help your muscles function better, increase your athletic performance and reduce muscle fatigue," Falzarano explains.
