these are long, at least 24", so you can scrunch them up for added warmth.  they are a medium weight slightly open knit, but not cheap.  if you look at the photo, you can see the model's shoe through the fabric, which gives you a clue they are not dense.

they have a nice fluted edge on one end.

the green is darker than the photo, more of a grass green.  from what other reviewers said, it seems these colors tend to be brighter/darker than the photo shows.

4 stars for not true to color, and quite a bit longer than expected from the photo.
