Best Answer: Boxers tend to be loose and shaped like shorts. Briefs are more of a snug fit and have no leg. A compromise between the two styles has been developed, called boxer-briefs that has qualities of both. Boxers are great for feeling some freedom, but briefs are good for keeping support. I like boxers for when I am relaxing but briefs when I run.
A boxer brief has longer legs than a trunk. Trunks inseam is normally only about 2â3 inches at most. Boxer briefs have somewhere around 6â8 inches of inseam. Trunks donât have a functional fly, whereas boxer briefs sometimes do have one. The rest of the underwear is structured the same.
