This is a great pair of Lululemon men’s Sleek black stretch chinos that are a size 40/31. When measuring the waist though, they are closer to a 39 inch waistband than a size 40. The hips are 23 inches across, the rise is 12 inches, and the inseam is 31 inches. The pant legs are 8.25 inches wide at the hem. They are made of a soft material that is a blend of nylon and spandex. The logo is above a seam in the back left leg at the knee bend.
