Cincinnati athletic director Mike Bohn said in a statement that the Under Armour deal combines "two hot brands." Cincinnati finished 9-4 in football last season, losing to Virginia Tech in the Military Bowl. Its men's basketball team won its opening game in the NCAA tournament before losing to top-seeded Kentucky.
Bearcats football coach Tommy Tuberville previously coached at Texas Tech and Auburn – both Under Armour partners.
Under Armour said in a statement that it will "exclusively design and supply the footwear, apparel and equipment for training and gameday uniforms for each UC's 19 men's and women's varsity athletic teams."
Under Armour's other college partners include Notre Dame, Navy, Northwestern and the University of South Carolina. Last month, Under Armour said it was extending its deal with Boston College for 10 years.
