Wind Barrier
I enjoy going on walks (almost) everyday. What I don't enjoy is when the wind whips into my ears. It makes me magically turn into an angry pedestrian. For a quick (and free!) solution I sliced open the sides of an old A-shirt (a.k.a. wife-beater), wrapped it around my head, and tied the ends together in the back.
I would have put my money on "bag lady", but it looked equal parts "doo-rag" and "religious turban". And I found it to be successful!
