I am obsessed with the lululemon Vinyasa scarf ($48) — so much so that I even gifted a few of these to friends over the holidays. Made from supersoft, moisture-wicking material, the snaps on each end allow you to customize how you choose to wear it: wrap it snug or wear it loose over the shoulders — the possibilities really are endless. (You can even shape it into a vest!) In this cool San Francisco weather, and with eight colors to choose from, I can't think of a better way to bundle up after yoga class.
