Abstract: An undergarment is provided for wear by men during work or recreation activities in the style of a pair of boxer type shorts. A partitioning liner is secured at the inside of the shorts and includes a cup portion adjacent to the front of the shorts. The cup portion is slotted or open in the front to form first and second partitions for positioning in the clefts on either side of the groin of the wearer to prevent chafing. A first panel of gusset secures the first partition to a first location on one side of the front of the shorts. A second panel or gusset secures the second partition to a second location on the other side of the front of the shorts spaced from the first location. A third panel secures the bottom of the liner to the crotch of the shorts. The independent suspension or coupling of the partitioning liner assures that the partitions remain securely in place without riding up and down with the shorts.
