Republican presidential candidate former Pennsylvania Sen. Rick Santorum, center, looks at a display of his official, Santorum for president sweater vest, at the Bemidji Wollen Mills store, with owner Bill Batchhelder, right, during a campaign stop at the vest manufacturer Sunday, Feb. 5, 2012, in Bemidji, Minn.
Rick Santorum's sweater vests have been a regular figure in the news ever since the Iowa caucus. The sweater vest took on a life of its own with its own Twitter account and Pinterest board. Santorum has fully embraced the sartorial attention, adopting the slogan "don't let sleeves slow you down." He began offering the sweater vests to those who donate $100 or more to his campaign, and today visited the factory in Bemidji, Minn. where they are made.
