Welcome to the Family

Underdogs don't prove others wrong, we prove Ourselves right

Philadelphia is the best city in the world, no matter what anyone else says. As a fellow Underdog, you know the true value of our city and you see it's hidden potential.

We created Underdog Apparel to start a movement; a tribe of people who are committed not only to celebrating our incredible community, but also to creating a better future for the next generation.

That’s why 100% of the proceeds from our products are used to directly fund programs that improve the lives of our city’s youth.

Philadelphia has only one future, and we owe it to ourselves to make that future the best it can be.

It’s time to show the world what Underdogs are made of.

It's time to prove ourselves right.
