It's like a kid in a candy store.

On Sunday, sweater-vest-loving GOP presidential candidate Rick Santorum will visit the Lake Bemidji, Minn., manufacturing plant that makes his famous sweater vests for sale on his campaign website.

Bemidji Woolen Mills, founded in 1920, has been family owned since it was created in an effort to produce "the highest quality, authentic outdoor woolen apparel for the early logging era in Minnesota and surrounding states", according to the website.

The sweater vest has become a signature fashion item for the former Pennsylvania senator who has donnned one frequently on the campaign trail. Earlier this month the campaign began offering them to supporters who donated $100 or more to help fuel the Iowa caucuses winner's presidential bid.

Bill Batchelder, fourth-generation owner of Bemidji Woolen Mills, told The Bemidji Pioneer last month that the plant was rushing to fill the influx of orders.

"We're not exactly sure what our daily capacity is, but all hands are on deck. Our employees are extremely excited to be a part of this," Batchelder said.

Snuggies and Slankets beware, Rick Santorum's sweater vest is apparently the new fashion "it" item -- at least, among the GOP presidential candidate's supporters.

Santorum's presidential campaign has made $100,000 so far -- at the going rate of $100 apiece for the official version of the famed and ubiqitous fashion accessory that the former US Pennsylvania senator wears at nearly every campaign stop.

"Perfect for demonstrating solidarity with true conservatives, this vest is a great way to show your support for Rick. It's 100 percent cotton, made in the USA, comes in grey and is yours for your contribution," reads Santorum's website.

Santorum backers in South Carolina will be able to get a new special editon sweater vest. The campaign will add a new color: Blaze Orange so that hunters can don it in the field.

In addition to the Santorum insignia, it will include another nod to Second Amendment enthusiasts on the sleaveless wonder:"The Right to Bear Arms."
