Tights comprising a heat retaining fabric and a heat dissipating fabric, wherein the heat retaining fabric is configured to be arranged in portions of a front of the tights, each of which covers an entire belly of the quadriceps femoris muscle, and in portions of a back of the tights, each of which covers an entire belly of each of the biceps femoris muscle, the semimembranosus muscle, and the semitendinosus muscle, when the tights are worn, characterised in that the heat dissipating fabric is configured to be arranged in a portion of the tights that goes all around the waist and covers the ilium, the lower abdomen, and bellies of the gluteus maximus muscle and the gluteus medius muscle, when the tights are worn, and the heat retaining fabric is not arranged in the portion of the tights that goes all around the waist, and wherein the heat retaining fabric is a moisture-absorbent heat-generating fabric and the heat dissipating fabric is a water-absorbent quick-drying polyester fabric, the moisture-absorbent heat-generating fabric is a woven or knitted fabric made from a spun yarn formed from a blend of highly crosslinked polyacrylate fibers and polyester fibers that are twisted together and in which the amount of the highly crosslinked polyacrylate fibers is 10 to 40% by mass, and the water-absorbent quick-drying polyester fabric is obtained by treating fibers with a hydrophilic polyester resin treatment agent which is absorbed in the fibers, and the fabric has a water absorbability which is 20 seconds or less as measured in accordance with JIS L 1907, and a drying time of 80 minutes or less as measured in accordance with ISO 17617-2014 A1. wherein the heat retaining fabric is configured to be arranged in portions of a front of the tights, each of which covers an entire belly of the quadriceps femoris muscle, and in portions of a back of the tights, each of which covers an entire belly of each of the biceps femoris muscle, the semimembranosus muscle, and the semitendinosus muscle, when the tights are worn, characterised in that the heat dissipating fabric is configured to be arranged in a portion of the tights that goes all around the waist and covers the ilium, the lower abdomen, and bellies of the gluteus maximus muscle and the gluteus medius muscle, when the tights are worn, and the heat retaining fabric is not arranged in the portion of the tights that goes all around the waist, and wherein the heat retaining fabric is a moisture-absorbent heat-generating fabric and the heat dissipating fabric is a water-absorbent quick-drying polyester fabric, the moisture-absorbent heat-generating fabric is a woven or knitted fabric made from a spun yarn formed from a blend of highly crosslinked polyacrylate fibers and polyester fibers that are twisted together and in which the amount of the highly crosslinked polyacrylate fibers is 10 to 40% by mass, and the water-absorbent quick-drying polyester fabric is obtained by treating fibers with a hydrophilic polyester resin treatment agent which is absorbed in the fibers, and the fabric has a water absorbability which is 20 seconds or less as measured in accordance with JIS L 1907, and a drying time of 80 minutes or less as measured in accordance with ISO 17617-2014 A1. <EOS>
