As part of Champion Athleticwear‘s “Be Your Own” campaign, it’s giving fans the chance to swap out any pre-owned pretender hoodie for a new Champion hoodie. The best part? It’s free.

“It’s our way of celebrating Champion’s role as a style icon,” says John Shumate, vice president of global marketing.

The inaugural “Hoodie Swap” is happening at participating Champion stores and outlet locations on Nov. 19 from 11 a.m. to 2 p.m. or until supplies last.

To kick off the event, Champion’s Global Culture Consultant Saweetie will be the first to swap a hoodie at the Champion Heritage Store in Los Angeles, California.

“I’ve been a fan of Champion since high school when I fell in love with the comfort, style, and fit of my first-ever Champion hoodie,” adds Saweetie.

The event limits one swap per customer, and participating locations include:

Champion will donate all swapped hoodies to Refried Apparel, a sustainable lifestyle brand that will turn the recycled fabric into handcrafted garments. Champion isn’t the only brand making waves in sustainability as of late. Nike recently announced a new apparel line called Nike Forward, which uses 70% recycled content by weight and an average of 75% less carbon (compared to its traditional fleece).
