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.
With boxer briefs the legs are longer ...they extend farther down your thighs. With trunks, the legs are shorter and squared off; they look like a pair of tight-fitting shorts or, more from where the name came from, a style of mens square cut bathing suit popular back in the 50's and 60's called ...trunks.
