I purchased this to block wind and supplement winter wear.  I wanted a scarf long enough to "double" and wind around neck.  Even though it looked thin at first, there is more than enough material to fold over and double up.  I noticed warmth and when walking, I have to untie the scarf.  It seems to get too warm for me.
It does the job for keeping me warm, it's long enough, fashionable to match mostly all of my outerwear and the price is right.
