About those woolly mittens that U.S. Sen. Bernie Sanders wore to the presidential inauguration, sparking endless quirky memes across social media? They’ve helped to raise $1.8 million for charitable organizations in Sanders’ home state of Vermont, the Independent senator announced last week.

The sum comes from the sale of merchandise with the Jan. 20 image of him sitting with his arms and legs crossed, clad in his brown parka and recycled wool mittens.

Sanders put the first of the so-called “Chairman Sanders” merchandise, including T-shirts, sweatshirts and stickers, on his campaign website Thursday night and the first run sold out in less than 30 minutes, he said. More merchandise was added and sold out by Monday morning.

“Jane and I were amazed by all the creativity shown by so many people over the last week, and we’re glad we can use my internet fame to help Vermonters in need,” Sanders said in a written statement.

Sanders’ mittens were made by Jen Ellis, a Vermont elementary school teacher who has a side business making mittens out of recycled wool. His inauguration look, also featuring the winter jacket made by Burton Snowboards, sparked countless memes from the photo taken by Agence France-Presse.

The groups that will benefit from the proceeds of the “Chairman Sanders” items include Area Agencies on Aging to fund Meals on Wheels throughout Vermont, Vermont community action agencies, Feeding Chittenden, Chill Foundation, senior centers in Vermont and Bi-State Primary Care for dental care improvements in the state, Sanders’ office said.

Sander’ attire has also sparked other charitable endeavors. A crocheted doll of Sanders in his garb was auctioned off online and Burton Snowboards donated 50 jackets to the Burlington Department for Children and Families in Sanders’ name, his office said.
