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.

Jawn with a Purpose

Join us in showing pride in our city while making a positive impact in our community.

A Noble Cause

100% of all proceeds go to the (Be)Philly Foundation where they’ll be used to directly fund proven programs that improve the educational and economic outcomes of our city’s youth.

Swag With Spirit

We won’t just focus on athletes or public figures; we’re going to celebrate you, the Real Philadelphians, the unsung heroes, the true Underdogs that make our city great!

Homegrown Designs

All our products are made at home, designed by local artists, produced by local artisans, and carefully crafted for the people we serve. Philly centric, Philly proud.

A Message From Our Founder

Dear Philly,

At each critical moment of my life, there was someone who believed in me.

Whether my family, my friends, or my fellow Philadelphians, I have felt the overwhelming love and support that has helped reach my dreams and potential on and off the field. Now it’s my turn.

This fall, Underdog Apparel will soft launch a limited collection of apparel items that I hope will inspire you, motivate you, or at least make you smile. Items that I hope you wear with pride. Items that I hope, will make a difference.

All proceeds from Underdog Apparel will go through the (Be)Philly Foundation to fund evidence based programs that directly improve the lives of Philadelphia youth. Every collection will also be designed, printed, and packaged right here at home.

I’ve assembled a wonderful team of Philadelphians to bring this vision, brand, and foundation to life. I am forever grateful to my teammates who have lent their faces to this cause. And thankful to any person who strives to leave this city better than they’ve found it.

Underdog is a mentality. Underdog embodies the true Philadelphia spirit. Beat up but never beaten, disadvantaged but never defeated. Counted out, written off, but always believing we have the chance to snatch victory from the jaws of defeat.

You can’t be an underdog if you believe the haters, and more importantly you can’t be an underdog without valuing yourself. This city owns this spirit. This city thrives on its haters. This city knows it’s worth. Which is why we are all Underdogs.

Underdog is committed to building a tribe of people who want to see a better future for the next generation. I want the city of Philadelphia to know that I believe in it, and our young people to know that we believe in them. Together, I know we can make a difference and this is only just the beginning.

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

A Hungry Dog,
Jason Kelce
