I was looking for something lightweight that would keep my ears warm when I go walking. I was eager to try these but disappointed that it didn't keep my ears as toasty as I would have liked. Great when the temp is 40 or above, but when the temp is below 35 I need something more substantial. Also I am somewhat petite and these don't fit very snug against my entire ear. They are better than nothing and don't mess up my hair so that is a bonus.  I will admit that my ears do get cold easily and I am walking at a very brisk pace.
