On December 3rd, Glaceau and Smartwater staged their annual Elf Party (Facebook page) at San Francisco's Broadway Studios, designed to celebrate with friends, to look back on the past year, and to give back to the children in need. All guys don their best Elf gear complete with tights and ears. The gals dress up in their best and most creative holiday outfits, filling the room with Ms. Clauses, Vixen the Reindeers, Snow Women, and more.

Over the past nine years, the Elf Party has benefited charities like BayKids, My Two Front Teeth, and the Family Giving tree.
