The agreement with the Naval Academy Athletic Association, which makes Under Armour official outfitter of all 33 men's and women's teams, also includes marketing and promotional opportunities.
The affiliation is Under Armour's 12th Division 1 all-school partnership.
"Under Armour is extremely proud to outfit the outstanding men and women who not only represent our home state of Maryland but also uphold the highest standards of the true student-athlete," Matt Mirchin, Under Armour executive vice president of global marketing, said in the announcement. "The Naval Academy Athletic Association's commitment to brotherhood, tradition and values is on full display across its athletic teams."
Chet Gladchuk, the Naval Academy's director of athletics, called Under Armour a leader in sports performance that is expected to give the student athletes a competitive advantage.
