Support the City of Brotherly Love and one of the greatest Philadelphia Eagles of all time in style with this Retro Crewneck from Underdog Apparel. The brand was founded by longtime center and Super Bowl champion Jason Kelce, with proceeds going to the Be Philly Foundation, a local charity supporting the city's youth. Made from soft cotton with a warm and breathable French terry lining, this pullover is perfect for chillier game days at Lincoln Financial Field or brisk days around the city. The rib-knit trim moves with you effortlessly, and the vintage-inspired graphic printed on the front displays your timeless love for the Birds in style.
