Underpant garment

Abstract

An underpant garment worn in a state of being substantially in close contact with a surface of a lower body of a wearer includes a main constituent portion made of stretchable materials that include a first-type material and a second-type material. The first-type material has a straining force greater than a straining force of the second-type material. In the underpant garment, the first-type material is arranged in regions such that in each region the first-type material covers at least a region including a part of musculus gluteus maximus, a part of musculus gluteus medius, a part of musculus tensor faciae latae, and a part of tractus iliotibialis, and the second-type material is arranged in regions other than the regions where the first-type material is arranged. This allows the wearer to smoothly shift from a static state to a dynamic state such as a running state, and helps prevent a displacement of the center of gravity when the wearer is in motion.
