The Turtle's Neck

Being a commuter in San Francisco, I've learned the proper way to prepare for the weather. I wear layers and always carry the best multi-function article of clothing ever, The Turtle's Neck.

You can wear it as a scarf, a hat, or a band to cover your ears.

The best use I've found for it? An emergency shelter for my digital SLR. San Francisco fog trembles and runs.
