Boxer briefs are a type of men's underwear that combine the features of both boxers and briefs. They are typically made from stretchy materials like cotton or spandex, providing a snug fit that offers support while allowing for movement. The length of boxer briefs usually extends to the mid-thigh, which helps prevent chafing and provides additional coverage. These undergarments are popular for their comfort and versatility, making them suitable for various activities, from everyday wear to sports. Boxer briefs come in various styles, colors, and patterns, catering to different preferences and fashion choices.
