I used to walk to work in Chicago, about 20 minutes each way. I would freeze trying to keep my scarf wrapped tight enough and keep the hat on my head. I really wish I would have had a SNOOD to keep my head, neck and ears warm and cozy. Also, it eliminates having to have 2 different cold weather accessories!
There are a couple of versions that I have seen out there. One is like an "infinity" scarf that can wrap multiple times around your neck and then drape over your head. The other version is a hat with really long ties that you can wrap around your neck. I love both and can't wait to sport one this winter!
