Nike Golf DriFit pants, men's size 35x30. These are across between khaki and brown in color, with a very faint heathered-type pattern. The close-up photos show the color most accurately.

There are silicone dots at the waistline to help them keep from sliding down. There are small square perforations  on the back of the legs at the knee area (I'm assuming this aids with articulation at the knee). There is a small slit at the bottom of the leg opening. Fabric is 53% nylon, 42% polyester, and 5% spandex.
