These convertible 3/4 pants are made of stretchy nylon and are lightweight at 290g. Worn only once, they are still in great condition. Purchased as a B-grade item from mont-bell. There is a faint white line of discoloration above the knee. It didn't affect wear. Please check the 6th photo. I wear other colors of this style often because of their stretch and comfort. They are easy to layer and regulate body temperature, making them a recommended style. - Brand: montbell - Model Name: Convertible 3/4 Pants Women's - Material: 92% Nylon, 8% Polyurethane - Weight: 290g - Size: M - Features: Stretchy, 2-way design Thank you for looking.
