Jason Kelce is bidding adieu to the NFL, and in collaboration with Jason's clothing line, Underdog, this limited release reps one of the greatest Eagles ever and one of the greatest centers to play the game in super-soft style. Pay homage to a Philly legend, now and forever.

A portion of profits from the sale of this tee will benefit (Be)Philly, a non-profit foundation fighting for a brighter future for the next generation of Philadelphians.
