In collaboration with General Mills, NFL icons Jason and Travis Kelce are launching their own breakfast cereal called the Kelce Mix. The cereal combines their three favorite brands: Cinnamon Toast Crunch, Lucky Charms, and Reese’s Puffs, and will be available in stores starting in September. The venture marks a nostalgic moment for the brothers, who both have a love of breakfast cereals going back to their childhood. Alongside the Kelce Mix, General Mills is also releasing four limited edition collectible boxes featuring the brothers' top cereal picks.
