The Underdog Collection
We’re teaming up with Jason Kelce’s Underdog Apparel to launch a special collaboration—celebrating American craftsmanship, community, and the grit that brings them together. Jason was hands-on from start to finish—helping to design a collection of everyday staples:
Every piece is made entirely in the USA, supporting the people and places that define our mission. It’s a partnership rooted in quality and the belief that making here matters.

From The Ground Up
When Jason Kelce set out to build Underdog Apparel, he wanted more than a clothing line—he wanted to stand up for the places and people that shaped him. That mission brought him to American Giant. Together, we’ve created a collection rooted in shared values: hard work, American manufacturing, and pride in the process. From fabric to fit, Jason was hands-on every step of the way. The result is a line of everyday staples—two tees and a crewneck—made in the U.S. by people who care. This is just the beginning.
