Sports leotard

The invention provides a straitjacket for sports, which is not easy to cause excessive leg swinging. The sports tights (10) are formed by combining at least a high-tension portion (22) and a low-tension material having a lower tension than the high-tension portion (22) in a predetermined shape including a first cylindrical portion (16) surrounding a first leg, a second cylindrical portion surrounding a second leg, and a third cylindrical portion (20) surrounding a lower abdomen. The high-tension material is disposed so as to extend from at least the middle in the width direction of the third cylinder section (20) in a first direction toward the lower ends of the outer sides of the first cylinder section (16) and the second cylinder section in the width direction. 本发明提供一种不易产生过度的甩腿的运动用紧身衣。运动用紧身衣(10)是至少将高张力部分(22)与具有比高张力部分(22)的张力低的张力的低张力材料予以结合而形成为规定形状，所述规定形状包含包围第一腿的第一筒部(16)、包围第二腿的第二筒部以及包围下腹部的第三筒部(20)，高张力材料是以下述方式而配置，即，至少从第三筒部(20)的宽度方向中间沿着朝向第一筒部(16)以及第二筒部的宽度方向外侧下端的第一方向而延伸。
