These 180's are made of cashmere and they are really, really warm - especially when it's real windy and cold. I've gone for so many years with cold ears - I didn't realize what I was missing out on :). They are a snap to put on, fold nicely to pocket size, look good, and don't affect your ability to hear the goings on in the environment at all.

They are a bit pricey (the cheaper versions are made of polyester) but they are made well and should last a long time.

They are actually uncomfortably warm if they are worn when the temperature is above the mid thirties - i.e., when they aren't needed!

They are my ears' best friends! :)

Now, when I'm walking down 5th Avenue on the way to work, I shake my head in disbelief when I see people with their cherry red exposed ears being bitten by the wind! :)
