As shown in fig. 1, the footless underpants of the present disclosure comprise an underpants body 1 and at least one crotch cut strip 2.

The crotch-proof cutting strip 2 is fixed on the edge of the leg circumference of the underwear body 1, and the length of the crotch-proof cutting strip 2 is 1/3-4/5 of the length of the leg circumference of the underwear body 1. The leg circumference of the pants body 1 means a ring-shaped area where the footless pants fit the leg of the wearer. When the crotch-drilling-preventing cutting strips 2 are more than one, the crotch-drilling-preventing cutting strips 2 are not overlapped and are arranged in a tiled mode.

The length of the crotch-proof cutting strip 2 is 1/3-4/5 of the length of the leg circumference of the underwear body 1. The length of the crotch-proof cutting strip 2 is smaller than the length of the leg circumference of the underwear body 1, so that the crotch-proof cutting strip 2 is prevented from tying the thigh of a wearer, and the wearing comfort of the size-free underwear is reduced. However, since the crotch cut strip 2 is too short, the crotch problem cannot be effectively avoided, and therefore, the crotch cut strip 2 should preferably be at least 1/3, which is the length of the leg band of the pants body 1.

The ratio of the tensile elastic modulus of the underwear body 1 to the tensile elastic modulus of the crotch-proof cutting strip 2 is 1 (1.8-4.5). That is, the crotch cut piece 2 is more elastic than the pants body 1 to generate a sufficient force to prevent the pants body 1 from getting up, and the crotch cut piece 2 is more unlikely to be deformed.
