The pant is 80% cotton and 20% polyester, the material grip, the inside is slightly roughened and can be adjusted in the covenant by a cord. The pants in size. XL had a leg length (inside) of 83 cm, after washing only 80 cm and has a circumference of the thigh also 80 cm. I ordered the pants for my husband, he is 1,86m tall need the XL to the hip but has very slender legs. The pants fit is not optimal, slackens around the legs. Because he wanted only for the home to lie on the sofa, he has kept it. Unfortunately, the pants has been run in the wash. Now he's in his pants flood with too wide legs. The pants is more likely for someone with strong physique and a size of max. 1.80m. For sports, I would prefer a different material.
