Walter Camp, known as the “Father of American Football,” played and coached there, leading the team to 3 of its 27 national championships. In 1875 they kicked off their rivalry with the Harvard Crimson in “The Game,” a historic face-off they’ve repeated 141 times, with Yale leading the series 72-61-8 through the 2025 season. Inspired by the letterman jacket worn by the 1950 Yale football team, ours is made with a real wool body, leather sleeves, and white chenille patches and lettering.
