Boxing trunks are part of the iconic getup. Trunks normally sport the boxer's name or nickname on the waistband, and in the professional setting, they also feature the boxer's sponsors. While professional boxers have much more liberty in selecting their trunks, amateur boxers are sometimes assigned to wear either blue or red. One notable difference between fight trunks and normal shorts is that they do not feature pockets. This is because pockets could cause injury in a fight in the event that a boxer's glove or gloved thumb gets caught in it. Another odd feature of boxing shorts is that they usually sit up around the abdomen level. This helps to make the beltline more visible so a referee can more easily establish foul and clean punches.
