These comfortable slacks are made from a blend of nylon and polyester. They have stretch, making it very easy to bend your knees and sit. Size: Waist: 38 Rise: 24.5 Inseam: 75.5 Thigh width: 25.5 Leg opening: 21 Nylon: 89% Polyurethane: 11% Separate fabric: Polyester: 100% The inside of the fabric is soft and warm to the touch, with a medium thickness. In image 7, the pocket construction has overlapping stitching for a stylish look. ☆The fabric has a mixed color appearance when viewed up close, rather than a single color. They have been worn few times, and I don't think the knees or the seat have stretched. - Brand: ETERNOBELLEZZA - Size: 42 - Material: 89% nylon, 11% polyester ☆Please refrain from purchasing if you are concerned about minor details or are a perfectionist. Thank you for viewing.
