These are a black heavy duty nylon half gaitor. The pair come in at 3.5oz. On sale (clearance?) for $4.97 from $14.97. Picked up 2 pairs for myself and my girl and really like them. Zipper in the back, heavy duty clip in front for laces and heavy duty flat cord for under the foot. these will be great for jaunts in the nevada wilderness to keep the goram brush out of my socks.
