Gilas (Elegance) is a Philippine Eagle. It is one of the world's largest eagles; distinct for its majestic plumage on its head. The eagle is a symbol of elegance, strength and pride. It captured the winning spirit of the athletes. Gilas was inspired by the Filipino words Maliksi (agile), Malakas (strong), Matalino (smart), Mataas (high), and Matalas (sharp).

Originally, the mascot was supposed to be a Philippine tarsier until the Philippine SEA Games Organizing Committee (PhilSOC) changed it to the Philippine eagle.
