Boxer shorts are a type of loose-fitting men's underwear that provide comfort and breathability. Named after the shorts worn by boxers in the ring, they typically feature an elastic waistband and a buttoned or open fly. Made from lightweight materials such as cotton, silk, or polyester, boxer shorts are designed to allow free movement and airflow, making them a popular choice for everyday wear and lounging. Their relaxed fit contrasts with tighter alternatives like briefs or boxer briefs, offering a more casual and airy option.
