Swimming briefs cover the important part of the user's lower body with a triangular shape. They are more close-fitting and comfortable during activities and will also highlight the wearer's body shape. Brief swimming trunks slightly highlight the male lower body than other styles of swimming trunks, so some people wear other types of swimming trunks to avoid embarrassment. However, briefs are used in professional competitions such as men's water polo and diving. Because they have the advantages of modifying the body shape and facilitating large movements and strenuous activities, most swimmers use this style of underwear.
