Boxer briefs are men's underwear. They are tight like briefs but still have long legs like boxer shorts. They are popular and are worn by lots of teenagers and young men.
Boxer briefs are usually made of soft material and can be made in different colours. Some boxer briefs have an opening with buttons on the front. Others just have an elastic waistband and can be pulled on or off like briefs. The waistband is often a separate piece of elastic and is sometimes in a color. Some boxer briefs have elastic at the end of the legs, and stitching across the bottom.
